Wellspring Pawn - Humanities Source, #1

Book One of the Humanities Source Series, by Sheley Rayne The Handmaid's Tale meets 50 Shades of Grey - A sultry dystopian romance. The Warden of all Life is fatefully drawn by a God who treats his King like a Pawn. As the holy-appointed Sovereign Overseer, untouched and unseen, Harlan Garotte is the sole ruler of AMAS Dome, a self-contained biosphere. Due to sterility concerns with HIMM's chosen people, Harlan implements strict breeding laws with both species, the racially pure Lebensborn and the biologically inferior Grubbians.
When Mihanna, an alluring Grubbian woman, defies the divine order of HIMM and touches the Sovereign Overseer, the celibate leader's senses awaken. Mihanna's appearance prompts Harlen to test her genetics in his procreation program. When HIMM declares MiHanna the Optimum Source, who will conceive the next ruler, and matches her to the Prime Breeder, Harlen's brother, Harlan, is devastated. He's already committed an unthinkable act, which means facing the wrath of HIMM, a self-aware computer with a god complex who's threatening a population-wide annihilation.
Will one fateful touch ignite genocide or unite an all-species crusade?
