This is not your sweet sparkling vampire story. Old-school vampires have re-surfaced, responsible for brutal murders and more blood than anyone can cope with. In "Tangled Blood Lines", Cianna Fitzgerald, a young but "retired" crime scene investigator, finds herself back in a world she walked away from some years ago. She grew up in twentieth century Pennsylvania countryside knowing she possesses superhuman powers from her "Irish pixie" bloodlines. She had retired after a particularly tough case where the victim was her husband's twin brother. After her brief respite from murders and homicides, Cianna witnesses a killing where the murderer is a vampire. Her daughter goes missing soon after the killing. Cianna and the love she had once pushed out of her life, her estranged husband Declan, travel halfway around the world to try to save their child. As the mystery unravels, she learns that although she is a half-breed, the other half isn't "Irish pixie" as she grew up believing - weaving her into a more tangled history and frightening future than she had bargained for.
