Darkness Splintered

Risa Jones, half-werewolf and half-Aedh (angelic spirit), is pregnant by her former-soul-guide-Reaper lover, Azriel, and is being forced by vampires, rebel Aedh priests and her not-of-this-world father to search for the missing keys to the gates of Heaven and Hell. The keys keep getting stolen from her by dark mages in the Dark Angels series of paranormals by Keri Arthur.
