“The perfect kind of high-pressure adventure.” —TeenVogue.com
A New York Times bestseller!

Red Queen meets The Hunger Games in this epic novel about what happens when a senator’s daughter is summoned to the galactic court as a hostage, but she’s really the galaxy’s most dangerous weapon in disguise.

A Diabolic is ruthless. A Diabolic is powerful. A Diabolic has a single task: Kill in order to protect the person you’ve been created for.

Nemesis is a Diabolic, a humanoid teenager created to protect a galactic senator’s daughter, Sidonia. The two have grown up side by side, but are in no way sisters. Nemesis is expected to give her life for Sidonia, and she would do so gladly. She would also take as many lives as necessary to keep Sidonia safe.

When the power-mad Emperor learns Sidonia’s father is participating in a rebellion, he summons Sidonia to the Galactic court. She is to serve as a hostage. Now, there is only one way for Nemesis to protect Sidonia. She must become her. Nemesis travels to the court disguised as Sidonia—a killing machine masquerading in a world of corrupt politicians and two-faced senators’ children. It’s a nest of vipers with threats on every side, but Nemesis must keep her true abilities a secret or risk everything.

As the Empire begins to fracture and rebellion looms closer, Nemesis learns there is something more to her than just deadly force. She finds a humanity truer than what she encounters from most humans. Amidst all the danger, action, and intrigue, her humanity just might be the thing that saves her life—and the empire.

Ughhhhh So Good!!!

The diabolic was such a amazing book. It was so interesting and captivating. I read it in a day because it just kept me stuck. Also I love how mean and gruesome. It could be but also how loving, sweet, and sad. Can’t tell you how many times I cried. But it’s a really good book and deserves a total 5/5 stars. Also totally recommend this book to everyone it’s so good. But that’s enough to be said just read the freaking amazing book already!!

Very Good

I really enjoyed this book. The plot was well thought out and the characters were fantastic; each one had many angles and levels. I loved a new focus on humanity that I have yet to see in another book. I would definitely recommend it.

This book is intense, fast paced, and a great read. The plot is detailed and complex but not in a bad way. It does have romance, but not an exceedingly obscene amount. I would definitely recommend!
