"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." -- Amazon.
