Seventeen-year-old Tenja thinks she can handle anything. Bears, cougars, starvation, guards and demons are nothing for the skilled and dangerous girl. Living in a post-apocalyptic world, orphaned Tenja is forced to face these enemies on a regular basis. Trained from an early age in lethal hand-to-hand combat and survival skills, Tenja is a complicated individual with a spine of steel but a gentle heart. She is ready for any problem the world can throw at her. That is until the rebel warrior Ronan shows up in her life. Convinced that Tenja is evil because of the inverted cross on the back of her neck, Ronan reveals earth-shattering secrets that connect her to a vessel that is thought to have the power to bring down the invisible walls imprisoning and separating the demons from what is left of the human population. Possessed President Jenkins and his Elite are on a mad chase to find it. Only Tenja might hold the key to unlocking the vessel's mysteries. Tenja will fight desperately against her emerging vulnerable feelings of love and self-doubt. Haunted by visions and tattooed with a mark that seems to give her strange powers, Tenja will set out on a journey of self-discovery as she tries to protect her loved ones from the evil that stalks her. By the Blood is the first book of an exciting fantasy trilogy that will hold you breathless from the tender romance to the harrowing danger.
