Half of Heaven has plans for Mia and her patchwork family of Fallen angels and extraordinary humans - the plot, however, remains a mystery. Hell just wants them all dead, and the other half of Heaven? Well, they won't be handing her a medal any time soon. A new member has joined the group, and it's the last person Mia wanted back into her life. Or is he exactly what she needs? Either way, having him in their ranks only makes them a bigger target.
