Perfect Timing

Caterer Crik Duvall is bewildered. In the city he thought he knew, suddenly buildings grow, people incorporate animal powers, smart phones know it all, and vehicles defy gravity. He's been accidentally transported to a future where he's unwanted. To keep their past intact, the future's authorities must return Crik to the moment he left, a moment when he was dodging gunfire. That is, unless he can show he was vital to progress.
With his cat-woman guide, Tepper -could she be his distant descendant? -the duo dash around to suss out what makes Geotopia work so well for people and planet. Vigilante Voltak, protector of the status quo, pursues them to return the "Pastian" runaway before his allotted twenty-four hours are up. If by then Crik can prove he's their Founder, he'll be a celebrity in his new time.
