He's a hellhound guardian from the underworld. She's the veterinarian who accidentally saved his life. The fated mate bond between them? Impossible. Irresistible. And absolutely forbidden.
Anna Vaughn has spent years treating Houston's supernatural creatures in secret, convinced she's losing her mind every time a "normal" animal walks into her clinic and her instincts scream predator. But when a massive, wounded hellhound crashes into her emergency room at 2 AM, everything changes.
Kael Ashborne is six centuries old, battle-scarred, and bound to guard the gates between realms. He's never failed a mission. Never broken protocol. And he's definitely never felt the fated mate bond snap into place—especially not with a mortal woman who smells like antiseptic and has no idea what he really is.
The bond is permanent. The attraction is scorching. And Kael's superiors want him back at his post. Alone.
