In Her Shadows: A Tribes of the Vampire Novella. Tribes of the Vampire, #4

Some secrets never die. Some loves are worth the risk. When Olivia Baker was ten, she witnessed a massacre-a pile of slain vampires burning in the dawn light. She never revealed who did it, and that secret has haunted her ever since. Now, fourteen years later, Olivia lives in the shadows of supernatural politics, caught between the warring factions of the vampire tribes. Some elders want her dead to silence the truth forever.
Others want her turned, believing the key to the massacre lies in her blood. Her only hope for survival is Jaxon, her brooding and dangerously seductive vampire guardian. But Jaxon's loyalty is as uncertain as his intentions, especially when his own dark past intertwines with hers. As ancient enemies close in, Olivia must navigate a world where monsters wear familiar faces and passion can be as lethal as betrayal.
She can't afford to trust Jaxon or her own growing desire for him. Because in a world ruled by immortals, one wrong move could mean the difference between love and death. In Her Shadows is the fourth book in the Tribes of the Vampire quartet, starting with Redeemer of Shadows, The Jaded Hunter and Eternally Bound. Perfect for readers of J. R. Ward's Black Dagger Brotherhood series, Kresley Cole's Immortals After Dark series, and Nalini Singh's Guild Hunter series, In Her Shadows blends brooding vampire romance, forbidden love, supernatural political intrigue, and dark protector themes into a gritty, atmospheric tale of survival and desire.
