The Breeds are humans altered before conception with the DNA of the predators of Earth. But although they all carry the genetic material of beasts within them, Cassandra Sinclair stands apart. A unique mix of wolf, coyote and human, she is revered by many—but preyed upon by others. She is fiercely protected by her community…but no one manages to stop her when she slips away one day to offer her body in exchange for her sister’s safety.

The man she succumbs to surprises her by unleashing her inner animal in ways she never dreamed possible—and provokes her deep, furious rage. To Cassie’s shock, he is the mate she has long awaited. She may never be able to forgive his deception. Still, as dangerous enemies track her, and as the threat of all-out war between Breeds and the humans who despise them hovers in the air, they must join forces and hold fast to each other.

But the passionate union between them holds a potential that could change the world—and some will do anything to stop it…
