Geneslide

You don't miss your genes till they turn prehistoric. In a last half-second effort to stave off nuclear holocaust, the Timekeeper starts evolution running backward. And man, is he pissed. So pissed, he's decided to backdate humans right out of existence. As people morph in and and out of prehistoric animals, a ragtag band led by Galloping Ariadne and Philip the Assault Otter careens through time, fighting off dinosaurs and time storms as they try to convince the Timekeeper, now convinced he's cruise director aboard the Titanic, to give humanity one more chance. But at every turn they must fight off a right-wing cabal led by a megalomanic saber-tooth who believes the true top of the food chain lies only in godhood.
His godhood. No others need apply. A wild ride up and down the evolutionary tree, Geneslide combines  action, humor, political satire, and a most unusual love story in a tale that will sweep you along on an adventure unlike any other.
