Siobhan Williams has always been a brilliant individual, graduating high school early and excelling academically. Early in her career, she joined the FBI and became one of the youngest agents in her unit. As a member of the BAU's Crimes Against Children division, her team is called in when there's a concerning surge in kidnappings - 13 children vanish within two months, all in her home state of California. It's been nearly a decade since Siobhan left her hometown, but she and her partner step up to lead the investigation into these baffling disappearances. Together with a diverse group of fellow agents - including a werewolf, a bear shifter, a Fae, and a vampire - they find themselves entangled in a conflict between the divine forces: Arawn and Scàthach, a struggle that transcends good and evil, involving the living, the undead, and the afterlife. With her plate already full, the last thing Siobhan expects is to have a potential mate getting under her radar. Tiernan Hathaway, the Alpha of his pack for nine years, has never found his destined mate, though he recalls a strong connection to the second eldest daughter of the previous Beta, Siobhan. He hadn't seen her in almost a decade, as she only communicated with her family. However, their paths cross unexpectedly when the FBI approaches him about the alarming number of supernatural children going missing. As the situation unfolds, Tiernan discovers a shocking revelation that sets off a chain of events tied to the brewing battle between the underworld deities.
