6 Thrillers With WTF Endings…Explained

Hello there, fellow bookworms. Today’s post will be dedicated to psychological thrillers or mysteries that have completely blew us away with some of the craziest endings! Isn’t that such an ideal way to make a book have a lasting impression on us? I will also be including a small explanatory paragraph on the ending under each summary/review, so if you’ve yet to read the book, just steer clear from the “Spoiler Alert” section. Alright readers, if this sounds appealing to you, then stick with me and let’s dive right in…

I. Behind Her Eyes by Sarah Pinborough

When Louise arrives at work on Monday, she meets her new boss, David, the very married man she met and kissed at a bar the night before. And then Louise bumps into Adele, David’s wife. The only thing that is crystal clear is that something in this marriage is very, very wrong.

*sigh* Where do I start with this one? Behind Her Eyes will take you on – as one of the book’s characters said – a “mindf*** crazy” ride. You think you know what the plot is about, but you don’t.

The concept behind the ending of Behind Her Eyes is just so bizarre and mind-blowing. It tackles a very rare condition in which people suffering from night terrors and lucid dreaming have a kind of, um, “otherworldly” superpower (but not the kind that you think). It’s evil, believable and so darn insane. The gigantic WTF ending is one you won’t be able to forget.



The big twist is that before Rob (Adele’s childhood friend) mysteriously died, he had actually switched bodies with Adele! He had met Adele’s husband David, killed himself (as Adele) then – in the final pages – killed David’s mistress Louise and switched bodies with her. By the end, David still thinks he got his happy ending with Louise, when it’s actually Rob who’s inhabiting her body, AND of course, who’s been narrating this entire book.


II. I Know Who You Are by Alice Feeney

Actress Aimee Sinclair comes home one day to discover that her husband is…gone. Leaving his wallet, keys and phone behind. Aimee, as you might’ve suspected, is the prime suspect. She claims she has nothing to do with it, and while trying to figure it all out, there’s a mysterious stranger that’s stalking her

This book has the creepiest, most unsettling, WTF twist ending you’ll ever read. Almost as similarly twisted as Behind Her Eyes. This is a book that you’ll race through. I still have goosebumps and feel dizzy from the entire experience!

Aimee takes us back to when she was five, and my oh my, the things she has gone through. The things she has seen!! Those terrifying flashbacks make the plotline even more absorbing. The entire time, I felt both afraid of and in love with this woman. Excellent writing quality, and the character development is on point. You guys need to read this one. Now let’s talk about that ending…



This one’s a bit unsettling. Okay, here goes…

Aimee’s stalker turns out to be her husband, but wait for it – her husband is actually her own brother. When he was a child, he wasn’t happy with the fact that his sister abandoned him and went on to have a successful career. The creepier fact is that after marrying him, without her ever suspecting a thing, she got pregnant with – yep, you guessed it – her brother’s baby. After finding out about all this during the shocking ending, she seduces him for fear that he’s going to kill her, then soon cuts her psychopathic brother’s head and kills him for good. Yes. This book is DARK.


III. Before She Was Found by Heather Gudenkauf

For twelve-year-old Cora Landry and her friends Violet and Jordyn, it was supposed to be an ordinary sleepover–movies and Ouija and talking about boys. But then they decide to sneak out to go to the abandoned rail yard…Later that night, Cora is found on the tracks, bloody and clinging to life, her friends nowhere to be found. Soon their small rural town is thrust into a maelstrom. Who would want to hurt a young girl like Cora–and why?

The final pages of Before She Was Found were pretty traumatizing as we’re given a full account of what really happened on the night in question. I had to re-read the ending over and over again to believe it. The author uses the characters’ texts, diary entries and therapy sessions to tell the story. Those different formats made the experience much more addictive. Highly encouraging you to pick this one up, fellow readers. The reveal will blow you away.



Well, who exactly attacked Cora, you ask? It was Cora herself! She’s a mentally ill teenage girl, and in the rail yard that night, she had experienced a mental condition called “depersonalization/derealization” – a psychological experience that makes you detach from your own body. That’s what Cora did that night, she depersonalized and began to see herself from the outside, stabbing herself with a knife and hitting her head repeatedly on the train tracks.


VI. I’m Thinking of Ending Things by Iain Reid

In Iain’s I’m Thinking Of Ending Things, a girl and her boyfriend are on their way to a secluded farm to meet his parents. When the two take an unexpected detour, she is left stranded in a deserted high school, wondering if there is any escape at all. What follows is a twisted unraveling that will haunt you long after the last page is turned.

If you’re looking for a book that’s different from anything you’ve ever read, I’m Thinking Of Ending Things by Iain Reid might be the one for you. At first, I wasn’t sure where the story was going; there are entire chapters filled with incredibly deep conversations between a girl and her boyfriend about life, relationships…but the moody atmosphere of the book was so engrossing and the writing was compelling enough for me to keep cruising through, and then all of a sudden, a twist happened…and I freaked out! But that wasn’t all: all it took was ONE WORD in the final paragraph for me to question EVERYTHING I thought was true…it felt like a virtual slap across my face.



So I’m Thinking Of Ending Things, in fact, deals with a mental condition called “Dissociative Identity Disorder” (the first clue was when the girl said, “this is a no-mirrors day for me”: it’s very well-known that people with this condition can easily dissociate or switch alters when they look in the mirror, and that was confirmed when she kept getting phone calls from herself). Afterwards, we’re led to believe that she’s trying to end things with Jake, her boyfriend. BUT, in the end we realize that this young woman wasn’t actually the narrator of the story at all. It was her boyfriend Jake all along. He has a split personality and he’s actually created an alter of the girl he never got to ask on a date (the “girlfriend”), and the road trip he was on was really just symbolic of his journey/quest to answer the question that keeps nagging at him: whether he should “end things”, meaning “end his own life”. In the end, we find that out that Jake is a suicidal school janitor who finally reunites with all of his alters, all of them agreeing that yes, he should take his own life.


V. Verity by Colleen Hoover

“Somewhere up there is the house, and somewhere inside of that house lies Verity Crawford.”

My first thought the moment I finished this book was: “What the heck did I just read?!!

The book starts off with a bang: our protagonist Lowen Ashleigh witnesses something terrible happen right in front of her. Later on, we see that a man named Jeremy offers her the once-in-a-lifetime opportunity to continue a book series written by his wife/successful author Verity Crawford, whose injuries have left her unable to move or speak. But, is pursuing this job offer a good idea, considering the mysterious history of tragedies that Verity’s family has known, the elusiveness of why Lowen was really picked for the job, and the coincidental, horrifying occurrence that she had to witness at the beginning of the book?

Lowen moves into Verity’s home, and it’s not until she stumbles upon one of the author’s manuscripts that strange things start to happen around the house. Lowen is soon torn between her attempt to leave this house where she feels she’s going completely crazy, and her determination to unveil its secrets. Verity is going to disturb you, challenge your sanity and provide you with the most overwhelming experience.



Miss Verity has actually been faking her injuries all this time. As as result, her husband kills her in a fit of rage after her found out. We later discover that Verity’s manuscript (which just shows what a horrible woman she is) was just a writing practice! The incredibly controversial ending left us with two questions: is Verity the psychopathic liar we think she is, like the manuscript claims? Or is she innocent after all?


VI. Sharp Objects by Gillian Flynn

In Sharp Objects, Reporter Camille Preaker is facing a troubling assignment: she must return to her childhood home to cover the murders of two preteen girls. For years, Camille has hardly spoken to her neurotic, hypochondriac mother or to the half-sister she barely knows: a beautiful thirteen-year-old with an eerie grip on the town. Now, installed in her old bedroom in her family’s Victorian mansion, Camille finds herself identifying with the young victims—a bit too strongly. Dogged by her own demons, she must unravel the psychological puzzle of her own past if she wants to get the story—and survive this homecoming.

Sharp Objects is probably the creepiest thing I’ve ever read, and it was surprising to see that the TV adaptation starring Amy Adams captured the core of the novel so well. Gillian Flynn accumulates all these dark, real-life aspects that other authors usually shy away from and tackles them in a chillingly brilliant way. The story’s very well-executed and there’s always a bit of unease that pulls you in deeper and deeper the more you turn the pages. And brace yourself for the most sinister, unexpected ending you’ve ever read, and the scariest part is, the evil and psychopathy that leads to the shocking aftermath is in fact completely realistic.



It turns out that the actual twisted people in this story are Camille’s own mother and sister: while the mother was the one who poisoned Camille and her sister, almost killing them both, it was the sister who did all the killing, which we discover when we find out that the floor of her creepy dollhouse is in fact layered with actual human teeth.


What do you think of these picks, fellow readers? Which book completely blew YOU away that you thought, “what the heck did I just read!”?

  1. I have not read any of these, but have the last two on my bookshelf to read, so I did not read your spoiler for them. The others all sound exactly like a WTF did I just read. I hope you are staying safe and healthy Ludwig.

    1. Thank you for your well wishes Carla, hope you’re keeping well and safe too! I highly recommend the last two if you’re looking for something unique and dark. Sharp Objects is a VERY dark mystery with an unsettling final revelation, and Verity is a psychological thriller with SO MUCH evil 🙈 which sparked so many different reactions from readers back when it was released. Hope you enjoy both of these!! 😊
