She escaped death once ... but some monsters never let go.

Twenty years after surviving an attack that nearly took her life, Claire Thordis has buried her past beneath a new identity. Now a respected medical examiner in Kansas City, she keeps her secrets locked away and men at bay. But when two corpses walk off her examination table and an ancient ritual sends her best friend vanishing into an immortal realm, Claire's carefully constructed life unravels. A dangerously seductive fallen angel now haunts her dreams, and the memories she's outrun for decades are clawing back.
Seung Moon has spent decades suppressing the demonic hunger that awakened at age seventeen. Half human, half fallen angel, his thirst for blood was kept in check by a mystical tattoo-until one scorching night with Claire shattered all control. Now serving as her guardian again, Seung's limits are tested like never before. The monster inside him may devour them both, yet their desire is impossible to resist.
With demons closing in and an ancient ritual standing between Claire and her missing friend, she's forced to choose - lose her friend forever or work side by side with the fallen angel who risks shattering her heart.
