WILD ADV OF ERB HC DARK TIDES OF MARS

Barsoom is dying, its atmosphere thinning with each passing year, the seas that once flourished upon its surface dried up eons ago. When warrior-scientist Dat Voga is asked to become Helium's ambassador to distant cities that may provide a desperate chance at life for the people of Barsoom, he leaps at the opportunity. But even as this new hope dangles on a thread, a madman seeks to hasten the Red Planet's doom-and Dat Voga is hurled headlong upon an odyssey across the chasm of Time itself!
