Kennedy is the young, intelligent daughter of Alpha Warren and Luna Yara. As the oldest daughter and twin sister to the future Alpha of their pack, she is much admired by their pack and others. Unlike her sisters, from a young age Kennedy took after her mother, spending most of her life in the pack hospital, sitting in on medical classes and watching surgeries. Now, she is turning eighteen and she hopes to find her mate. For Kennedy, there is only one man for her, the dark and broody Quirin.

Alpha Quirin took over his father's pack at eighteen. After lying vacant for ten years, it took a significant amount of time to get it back into a functional pack. Once he did, the rogues began to approach him. Over time, he's created a strong, powerful pack of fighters who value strength, above all else. While pack wars are rare, it isn't uncommon for other packs to attack, wanting the wealth of Quirin's pack.

Quirin has always been drawn to Kennedy. He knows he isn't the right man for her, but when his wolf recognizes her as his mate on her eighteenth birthday, he's unable to reject her as he knows he should. Having expected to live his life alone, he knows nothing of being a good mate. The darkness inside of him, the hatred for Kennedy's father who murdered his, wars with his desire to let Kennedy fill him with her bright, cheerful light.

Can Quirin let go of the past? Can Kennedy heal the darkness inside of Quirin and teach his pack that physical strength isn't the only strength that matters? Or will Quirin's darkness overpower her light, extinguishing it forever?
