Is a world of perpetual sunlight and savagery the only hope for Earth's last humans?Ember, Seven, and their companions survived the apocalypse, but that was easy compared to the challenge they face now. These six improbable heroes must find a habitable world for twelve thousand people being held in stasis - the last remaining humans on Earth.The clock is ticking. Ember and the others are dying from contamination, and their only hope for a cure is to get the job done. With several terraformed worlds to choose from, the first was a bust. Sure, that planet was pleasant enough, until a solar eclipse occurred and billions of flesh-eating bugs emerged from hiding.With no time to rest, the team jumps to the second world, Coratune. Terraformed centuries ago and seeded with humans and other Earth life forms, Coratune seems promising. But the humans here haven't progressed as planned - they've gone feral. Forced by a dysfunctional robot into a harrowing journey across a hostile landscape, Ember and her companions find a glimmer of hope... but can hope endure in the midst of appalling savagery?
