The Gatekeeper (The Clans of Tagus)

Abandoned as an infant, raised among strangers, cursed by mysterious powers she tries to hide, Kylie Baker lives a solitary life - until secrets from the past thrust her headlong into an unfathomable future. She's the Gatekeeper, guardian to a portal between two worlds, and if a demon Warlord from the other side has his way, all hell's about to break loose on Earth.

Kylie must locate the one person who can explain what is happening . . . the mother she thought was dead. A shapeshifting warrior and his band of rogue werewolves are determined to keep them apart. Armed only with her instincts and a strange amulet, and befriended by a sexy cowboy and his telepathic dog, Kylie embarks on a passionate quest to find the truth.
