Jude Shea's life is turned upside down when he rescues a dog he names Joe. Even though Jude has enough trouble taking care of himself—he doesn't even have a job—he can't resist the animal that needs him. Then one night, a man shows up on his doorstep looking to claim Jude's new companion. As they run from a surprise attack, Jude finds out that 'Joe' is not what he seems.

Eoin Thral is a guardian from an alternate dimension, and once he leads Jude through the veil that separates their worlds, he transforms into a handsome hulk of a man known for his fighting skills, not the capacity for love. Jude finds himself immersed in Eoin's world, and he's faced with the fight of his life to secure a happy future for them both.
