An archaeologist unearths a cursed, ancient Roman and draws the ire of an evil witch in this romantic urban fantasy from the author of A Vision in Crimson.Quintus is a dutiful son and soldier, sent to Britannia to improve his marriage prospects and ensure the Druids never rise again. Roman soldiers destroyed the last Druid stronghold in a battle of blood and fire. So, he never expects to be sacrificed to their sacred bog, trapped forever by the gods below.Two thousand years later, Asenath Hayes discovers the most well-preserved body in history. And the last thing she needs is for him to wake up.As the young archaeologist delves into Druidic rituals to grasp why Quintus was offered to a Welsh bog and then resurrected, she is forced to complete her research with the "missing" body, dodge her ex-lover and mentor with his own agenda, and keep her gorgeous new houseguest under wraps.But, smitten with her as he seems, Quintus says he wants to go home.Asenath is drawn to Quintus by the secrets they share, even if it scares her. As Asenath is pulled deeper into the mysteries of the bog, she must risk everything to keep him from hell's cold grasp as she uncovers forbidden rites, awakened deities, and an attraction that transcends the ages.
