The best books with untrustworthy sibling relationships

Why am I passionate about this?

I have been absolutely entranced by complicated family dynamics and sibling relationships as long as I can remember. Particularly as they exist within the thriller space. I graduated with a degree in criminal justice which only fueled that fire as I learned so much more about psychology, the human mind, and the depths of human depravity. It was so natural for me to start exploring it in my own reading and writing.

When She Was Me

By Marlee Bush,

Book cover of When She Was Me

What is my book about?

Ever since that night, twin sisters Cassie and Lenora have been inseparable. As the sole permanent residents of Cabin Two, their refuge on an isolated Tennessee campground, they manage to stay away from prying eyes, probing questions, and true crime junkies. Just the two of them, Cassie and Lenora against the world. The peace and quiet is almost enough to make them forget what happened all those years ago. Almost.

Until a teenage girl camping at the neighboring cabin goes missing, and the memories come rushing back. Trapped in the isolating, claustrophobic wilderness, Cassie and Lenora must piece together the truth of what happened—and the sinister truth lurking in their own pasts—before it's too late.

Book cover of The Good Sister

Marlee Bush Why did I love this book?

I absolutely inhaled this book because of the main character. Sure, the story was suspenseful, murdery, and twisty—all the things I love—but it was the main character that kept me flipping pages. She was a joy to read. Being in her head was so fun and endearing even in the midst of such an intriguing thriller. I couldn’t help but root for her until the very end!

Book cover of Original Twin

Marlee Bush Why did I love this book?

I loved this book because reading it was a lot like watching a movie. The way Gleeson writes, you can picture it playing out on a screen in your head.

I absolutely flew through the chapters of this twin story with my heart in my throat. It felt so cinematic, dramatic, and knife-sharp. Plus, one of my favorite parts of a good thriller, the plot twist really got me.

Book cover of The Only One Left

Marlee Bush Why did I love this book?

I loved this book for so many reasons. The biggest reason is that setting! I loved how Sager truly used this gothic, cliffside crumbling manor to help tell the creepiest and twistiest tale.

Also I couldn’t have guessed that plot twist in a million years either and that’s always a plus when reading a thriller!

Marlee Bush Why did I love this book?

This is one of my favorite reads of all time. I love the way Jackson can make you so uncomfortable with her writing.

I love the way her characters are full of idiosyncrasies. I love the twists and turns. Mostly, I love the co-dependent, creepy, yet captivating sister bond she manages to display throughout this wild mystery!
