It is thousands of years into the future. The Milky Way and Andromeda galaxies have merged--planet Earth is uninhabitable. The human population (Total Humans) has migrated to other habitable planets but continues to dwindle while hybridized humans (Prototypes 1 and 2) vastly multiply. Fuchsia Starr, a human inhabitant of Luyten b, is desperate to locate her missing sister and will go to great lengths to find her...even if it means stepping over ex-husband and bounty hunter, Laramie Benson. After traveling through unfamiliar terrain on Ross 128 b, perilous encounters with cyborgs and intermittent time travel, their paths cross once again.
