The Prophecy (Guardians #2)
by Jessica Miller
Desperate, the angels enlist the two people most unqualified for the job. Jocelyn is an ex-angel trying to work for team good, but is only willing to do so by her rules. Sutton is half-angel half-demon and is battling himself every day, but when forced to work with the ex-angel who's hell-bent on making him go insane, Sutton finds himself teetering on the edge. Both wars could be a losing battle.
