Dovey didn't expect to fall in love after the age of 200, yet she can't stop thinking about Grant "Gib" Barlow, the gorgeous FBI agent who helped her crack her last case. A romance with an unbound is obviously a terrible idea, but for Gib, it could be fatal--because Dovey's employer, Elric Ostergaard, arguably the most powerful mystic in the world, also happens to be her longtime lover. Alas, Dovey's efforts to steer clear of Gib become impossible when her best friend, fellow mystic, and unapologetic romantic, Ursula Göransdotter, tricks them into a lunch date--during which Gib is alerted that a fellow agent has been murdered in his own home. The state of the crime scene, and of the body, seem to defy logic--but Dovey immediately recognizes the Crushing Spell, which could only be cast by a supremely powerful mystic--like her boss. When another agent is killed in the same manner, Dovey races to find Elric for answers. Meanwhile, the FBI body count rises, and it becomes clear that a rogue mystic is targeting the unbound agents, but why? What ensues is another missing magical trinket, a tense confrontation with Elric, a shocking discovery about Gib, and grave danger to all involved--forcing Dovey to navigate realm-crossing love triangles, supernatural power struggles--and ultimately, her own surprisingly vulnerable heart . . .
