Instead, she finds herself aboard an alien vessel, watching her children develop impossible capabilities that will allow them to survive in a world where normal humans cannot.But the aliens aren't the monsters in this story.For decades, the U.S. government has been secretly cooperating with desperate refugees from a dying world, trading human genetic material for medical breakthroughs that advance civilization by centuries. Sarah's family wasn't randomly selected-they were bred across three generations for this moment, designed to produce children who could bridge two species facing extinction.Now Sarah faces an impossible choice: accept her children's transformation and join a program that will replace human civilization, or fight for a return to normal life that could kill the only family she has left.As environmental collapse accelerates and enhanced human communities prepare to inherit the Earth, Sarah must decide whether love is strong enough to transcend the boundaries of species-and whether humanity's survival is worth the ultimate cost.Some partnerships demand everything. Some choices change the world forever.
