Boston Homicide Detective, Caitlin Reagan, walks a razor's edge, propping up her life on emotional constructs designed to help her manage grueling PTSD. She keeps her mother, boyfriend, and work separated and controlled, all in service to one horrible, tragic act she committed amid the Iraq war. But when the murder of a charity worker brings her face to face with the beautiful and charismatic philanthropist, Marcella Carson, Cait finds everything she thought she knew about her world, her life, and her very identity called into question. Sliding inexorably into an unsuspected Boston subculture, where creatures of myth and nightmare struggle to survive in a world of fading magic and proliferating public surveillance, Cait must face down her inner demons, rediscover her lost past, and catch an undead serial killer. In her first novel, Aoibh Wood explores a dark urban fantasy world through the eyes of a woman struggling to come to terms with Post Traumatic Stress, personal trust issues, and the belated realization that she is a lesbian. On the way, we meet a colorful cast of characters, from a Latino cowboy cop with a love of country music, to a ruthless vampire assassin and a retired serpent goddess with a passion for science. This book is intended for adult readers. It contains scenes of an intimate sexual nature, as well as themes and images of violence, sexual assault, and death

Two thousand years before Cait Reagan was a twinkle in The Morrigan’s eye, Weyna played handmaid to that very same Goddess in the year leading up to the Second Battle of Maighe Tuireadh, where the Tuatha de Dannan faced the forces of Fomori in a climactic final battle. But when Weyna stuns the assembled Gods and Goddesses by taking down the greatest fighter the Óșeni have ever known using a technique she never learned, she sets in motion a series of events that will ultimately lead to the discovery a long-buried secret two millennia later. In the present, Cait's sister, Aoife Reagan, a former member of Ireland’s Tacaíochta Faoi Arm, the Garda version of SWAT, is drawn to Boston for the funeral, only to find that it’s not going to happen. Cait died, but it didn’t take as Cait returned to the ranks of the undead somewhat posthumously. Unfortunately, Cait's soul has decided to go on walkabout, and she remains in a strange sort of stasis. In the meantime, Liz believes something larger is at work, and she has concocted an insane plan to draw out Cait’s killer and lead them one step closer to whoever is behind him. Aoife will impersonate Cait, leading the would-be assassin to believe they’ve failed. Now she just has to convince Aoife to be the bait, impersonate a nine-year veteran of the police department, and do it while chasing down a vicious creature of myth that is running loose in Boston and could destroy half the city.
