Half-Seraph and skilled fighter, Aidan Townsend could no longer live with the consequences of being a celebrated member of the Forces of the Fallen--so he walked away from it all. Now, he has created a new life for himself--a human life--as songwriter and lead singer for a successful Chicago band. And he keeps his angelic abilities carefully hidden-even from himself. Lucky Monroe is just an ordinary girl--or so she thinks. About to turn eighteen and with high school behind her, she's looking for a job, contemplating the possibility of college, and gradually coming to terms with her beloved grandmother's descent into early-onset Alzheimer's. Then her cousin Josh takes her to hear a popular local band-and she sees fiery wings extending from the back of the handsome and charismatic lead singer. Suddenly, she finds herself enmeshed in a world of Fallen angels, demons, and ancient deities--a world that promises knowledge of her newfound powers, as well as a budding romance, but also threatens all she holds dear.
