The challenge? Surviving the genocide of the human race when aliens attack Earth in the not-too-distant future. Sixteen-year-old Cassie, her brother Sam and her dad survived the first four gruesome waves of the attack. Together, the three wait out the titular fifth in a military base for survivors until school buses arrive to take all children to safety, including her brother Sam. Cassie, her dad and the rest of the adults are then divested of their weapons and marched into a bunker by their protectors. Cassie escapes, only to see her dad (and everyone else) brutally executed by their so-called protectors. She then embarks on a mission to rescue her brother. As in his previous efforts (The Monstrumologist, 2009, etc.), Yancey excels in creating an alternative world informed by just enough logic and sociology to make it feel close enough to our own. The suspension-of-disbelief Kool-Aid he serves goes down so easy that every piece of the story--no matter how outlandish--makes perfect sense. The 500-plus-page novel surges forward full throttle with an intense, alarming tone full of danger, deceit and a touch of romance. The plot flips back and forth with so much action and so many expert twists that readers will constantly question whom they can trust and whom they can't. Best of all, everything feels totally real, and that makes it all the more riveting. Nothing short of amazing. (Science fiction. 14 up)]] Copyright Kirkus Reviews, used with permission.

Cassie, sixteen, prepares herself for the fifth wave of aliens, the final takeover, fearing that she may be all that's left of humanity. She's alone until she meets "very good-looking" Evan Walker, and together they must figure out how to fight back. Yancey vividly portrays Cassie's existential crisis in a broken world: how to live, why to live, and what to care about. (c) Copyright 2013.
