Ghosts Bite Back - Alex Foulkes - Bog

A vampire and a ghost being friends is unheard of. It makes no sense. The two factions have despised one another for all eternity. But Leo the vampire and Minna the ghost have battled side-by-side: they're sisters-in-arms, they're best friends, and they'll have to work together to vanquish a new, deadly threat. Summoned to the Ghostly Realm for the murder of the Orphanmaster, Leo must complete three tasks to prove herself worthy of her unlife, each more treacherous than the last. Can Leo convince the Ghostly Realm of her innocence and earn her freedom, or will she be trapped there forever?
