It’s been a century of peace since Earth became a colony of an alien race with far reaches into the galaxy. Some die-hard extremists still oppose alien rule on Earth, but Donovan Reyes isn’t one of them. His dad holds the prestigious position of Prime Liaison in the collaborationist government, and Donovan’s high social standing along with his exocel (a remarkable alien technology fused to his body) guarantee him a bright future in the security forces. That is, until a routine patrol goes awry and Donovan’s abducted by the human revolutionary group Sapience, determined to end alien control.

When Sapience realizes whose son Donovan is, they think they’ve found the ultimate bargaining chip. But the Prime Liaison doesn’t negotiate with terrorists, not even for his own son.  Left in the hands of terrorists who have more uses for him dead than alive, the fate of Earth rests on Donovan’s survival. Because if Sapience kills him, it could spark another galactic war. And Earth didn’t win the last one . . .

“Fonda Lee’s Exo is a deeply immersive story that balances fantastic, original world building with spine-tingling adventure. Days after finishing, I was still thinking about it.” —Sabaa Tahir, New York Times bestselling author of An Ember in the Ashes series

Exo is my favorite type of sci-fi adventure—a novel that makes you question everything you think about our world . . . and what it means to be human.” —Kass Morgan, New York Times bestselling author of The 100 series

“This action-packed novel asks readers to consider alien technology, what it means to be human or nonhuman, and the gray areas in war, where neither side is completely good or evil. Ethical questions add complex layers to this exciting sci-fi offering.” —School Library Journal

“Lee constructs a plausibly alien future society and uses the premise to offer thought-provoking questions.” —Publishers Weekly
