From the author of the Seven Deadly Sins series and Hacking Harvard comes the final book in the science fiction trilogy Scott Westerfeld calls ‘;spellbinding.’One year ago, Lia Kahn died. A few days later, she woke up. She had a new body: Mechanical, unfeeling, inhuman. She had a new family: Mechs like her, who didn’t judge her for what she could no longer be. She had a new life, one that would last forever. At least, it was supposed to. But now everything Lia thought she knew has turned out to be a lie; everyone she thought she loved has been stolen away. And someone is trying to get rid of the mechs, once and for all. Lia will risk everything to save herself and the people she can’t live without. But not before facing one final truth: She can’t save everyone.
