Lost Souls is a graphic, intense, sexy novel by the High Priestess of weird horror, Poppy Z. Brite. Zillah, Molochai and Twig are vampires, belonging to an ancient species, akin to humans, but not human at all.
Vampires can breed with humans, but the birth always kills the mother.
These three travel the world, causing havoc, hunting and drinking blood. They visit New Orleans and the bar of Christian, a fellow vampire. Christian is older than the trio, and more sedate. However, an evening of Chartreuse and debauchery leaves Christian caring for Jesse, a young girl impregnated by Zillah. Eventually, she gives birth and dies.
