When six clones join Emmaline’s prestigious boarding school, she must confront the heartbreak of seeing her dead best friend’s face each day in class. The Similars are all anyone can talk about at the elite Darkwood Academy. Who are these six clones? What are the odds that all of them would be Darkwood students? Who is the madman who broke the law to create them? Emma couldn't care less. Her best friend, Oliver, died over the summer and all she can think about is how to get through her junior year without him. Then she comes face-to-heartbreaking-face with Levi—Oliver's exact DNA replica and one of the Similars. Emma wants nothing to do with the Similars, but she keeps getting pulled deeper and deeper into their clique, uncovering dark truths about the clones and her prestigious school along the way. But no one can be trusted…not even the boy she is falling for who has Oliver's face.

In this conclusion to The Similars duology, Emma must figure out who she really is, decide between two boys with the same face, and stop a dangerous plan based on revenge. Emma is still reeling from the events of her junior year at Darkwood. Not only is her best friend, Oliver, shockingly alive, but the boy she loves—his Similar, Levi—is still on the island where he grew up, stranded with his deranged creator. More importantly, she is grappling with who she really is. Emma can't accept the hard truths she learned last year and refuses to share her secrets with anyone, isolating herself from her friends and Ollie. But when more of the Similars' creator's plot is revealed, Emma and her friends will have to try to stop him from putting a plan into motion that could destroy everyone she loves.
