A Spectre in the Stream - The Slip Saga, #1

In a world gone mad with bloodlust, can a girl with a fragmented past use her inner monster to save a boy from undying predators? Earth, post-Apocalypse. Prisma longs to understand herself. Two centuries after humanity died, the claustrophobic immortal is grateful she's not driven by the thirst for blood plaguing every other enslaved survivor. But when she encounters a strange boy with a cryptic message about her origins, she fears his existence has made them both a deadly target. As Prisma's violently protective alter-ego gives her remarkable abilities, she and her curious companion track his mysterious origins through their decaying city and its virtual twin.
But she's horrified to learn of a vicious truth that sends her split personality into dangerous denial when a psychotic assassin and a desperate bounty hunter close in for the kill. Can she unearth the secret that will renew their stricken planet's hope? A Spectre in the Stream is the edge-of-your-seat first book in The Slip Saga science fiction fantasy series. If you like gritty characters, violent action, and dark-edged humour, then you'll love Simon Tull's fast-paced adventure.
