Characters ok Action ok Easy read great Escapism great Aliens travelling the multiverse great Aliens after water, one of the most abundant substances in the universe, not worth fighting for.. Good read but basic premise needs work. Maybe aliens looking for the Darwinian survivors of an apocalypse. That might work. Looking for the apprentices that transcend. That might work. Orb 3. Might answer this. Go Sophie (4 stars without the water).
