Dropout

Out of the earth apocalypse into a galactic meatgrinder. Caleb and the children have escaped the Humanist, flying out from Earth on the stolen Voloid spaceship. That escape is not without cost, though, as the ship is packed with enemies turned reluctant allies.

Hostilities run deep among aliens and humans, ex-HLF members and tribe members, and between the peacemaker ex-teacher Caleb and the warmongering tactician Lee. Balancing everyone’s needs, along with a failing spaceship, while being pursued by old enemies and facing new Galactic ones, will present a major challenge for them all.

They've dropped out of the battle for Earth, but the Galactic universe is no easier.

Dropout is the second book of the System Apocalypse: Liberty series, a standalone expansion in the bestselling System Apocalypse universe. It is an Apocalyptic LitRPG series that combines science fiction and fantasy elements with game mechanics. This series contains level ups, experience, a snarky AI shield-bot Companion, monsters (both human and otherwise), and a larger than life cast of characters.
