Monster Girl Base Books in Order

Accidentally activating an experimental machine sends a man between alternate versions of Earth every seventy-two hours. To survive their deadly environments, he recruits unusual companions and begins building a fortified base that can travel with them.

Dave and his companions reach another hostile Earth and begin strengthening their mobile territory. Ancient creatures and destructive tidal surges complicate survival, but a flesh-eating entity threatens something far greater than the safety of their base.

A world where dinosaurs survived presents immediate dangers for Dave and his companions, but worse dimensions await. As powerful interdimensional entities reveal their plans, the travelers must find a way to stop a threat with no safe refuge.

Drawing closer to a confrontation with mysterious interdimensional beings, Dave’s group lands on an abandoned Earth ruled by manufactured monsters. Surviving its endless night requires uncovering who created the creatures and what purpose their army serves.

An advanced species begins its final campaign across dimensions, leaving Dave and his companions little time to respond. They must locate the enemy’s homeworld and develop a weapon powerful enough to stop a conquest threatening the multiverse.
