New York Times bestselling coauthors Sharon Moalem and Daniel Kraus's terrifying sci-fi horror thriller takes place in a future that is much nearer than you think. It is a world where scientific experimentation is exploited for commercial profit and under-supervised cutting-edge technology creates a menace that threatens the very fabric of our existence.

Wrath is the story of Sammy, a lab rat instilled with human genes whose supersized intelligence helps him to engineer his escape into the world outside the lab: a world vastly ill-equipped to deal with the menace he represents. Modified through advances that have boosted his awareness of humankind’s cruelty in the name of science, and endowed with a rat’s natural proclivity to procreate regularly, Sammy has the potential to sire a rodent army capable of viciously overwhelming the human race. The key to Sammy’s capture and humanity’s salvation may be ten-year-old Dallas Underhill, whom Sammy temporarily adopts. But while Dallas and Sammy bond, time is running out for humankind: once Sammy sires his progeny, the exponential proliferation of his kind could spell the end of the world.

'Moalem and Kraus highlight some clever scientific concepts as the narrative details the variety of health problems that plague the Sammy Rats—and the sometimes barbaric methods employed to solve these issues . . . . Sienna and Noah prove ambitious and dynamic as pressure to perform brings out the absolute worst in them.' —Publishers Weekly

'Animals communicating or acting strangely is creepy; rats, in particular, give the book an extra level of sinister vibes. Add in that the rats can talk to humans, and you have an unsettling narrative that will leave you unable to look at rodents the same way again.' — Booklist
