The Invisible City
by Brian K. Lowe
Trapped one million years in the future, Charles Clee faces an Earth decimated, a cosmic playground where aliens hunt genetically-engineered nightmares, reborn monsters from Earth's dawn--and now Clee himself, as he races across the globe in search of the last time machine. But much as he wants to return to his time, he finds his new world may need him more. First in the "Stolen Future" trilogy.
