Nick Hunter's work for Habit County's Milleton Animal Shelter and Rehab involves rescuing lost pets and injured ferals and wildlife. He loves his job - until he finds out that not all the animals he brings in are from this realm. Then he loves it even more.

An unexpected inheritance means he can set up his own shelter - Echo Crossing - especially for refugees from other realms. But just as they're opening their doors, a rogue ancient beast (that not even his Sidhe girlfriend thought was still real) threatens Nick's life and the human domain. Now he and his new crew have to handle it without endangering the people they love - and without angering the Elders.
