I'm Voss Foster, author of the YA paranormal novel, Tartaros.
After the possession of his girlfriend by the Queen of Hell, Lilith, Daniel Tartaros is flung into a demon-ravaged future, where almost all members of his order of demon hunters have been exterminated. Everyone he knew is dead, and the most powerful demon in Hell wants him for her own. Yet, behind all this, there is a greater force than any of them could imagine, could ever hope to deal with, and he has his own plans for them, and for Earth.
