Gwen Mosely's life changes forever when she stumbles across a handsome stranger, unconscious and left for dead in the woods behind her farm. Cut up and bleeding, he's barely survived a vicious battle, but the real shock is how quickly his wounds heal—a gift he shares with Gwen's teenaged half-brother Chase.

Jarvis Donahue can't keep his eyes—or his strong, capable hands—off the sexy redhead who rescued him. He finds warmth of Gwen's smile and the desire in her eyes are impossible to resist, but there's a problem. Jarvis immediately recognizes Chase as a fellow Paladin in the making, a warrior born to defend mankind in the relentless battle against the Others. Neither Gwen nor the boy know it yet, but Chase will need Jarvis's help coping with the compulsion to fight that is written in his blood and in his bones. Although Gwen may hate him for it, Jarvis is duty-bound to secretly introduce Chase to the dangerous fate they both share.

As the barrier between the two worlds weakens, the threat grows perilously close to Gwen's farm. Jarvis is torn between protecting his lover, but without revealing his true identity, or betraying his people's secret and risk losing her forever.
