The Incunabulum Part Four

Nathanael Christian lives in a house bordering a
neglected old cemetery. Nathan frequently resorts to this
graveyard if only to escape from the abuse of the aunt
with whom he lives. But during one of his rambles among
its tombstones, he encounters, inside a mausoleum, a
strange girl named Phebe.
After discovering to Nathan that she's a vampire, Phebe
reveals that there's an incantation, in an ancient book,
which can undo her curse. Told that he must willingly
offer Phebe some of his blood for this spell to work,
Nathan agrees to help her seek and obtain this fabled
incunabulum.
