Dark and riveting, Morgan’s entry in the very popular dystopian, postapocalyptic YA subgenre blends science fiction, romance, and characters’ shadow sides with a mostly engrossing plotline. In a future lived on spaceships, long after the earth’s destruction, teenage delinquents are usually sentenced to die for their transgressions. Then 100 of them, who are deemed disposable guinea pigs, are instead sent to the ravaged earth in order to see if it is habitable for humans. Clarke, Wells, Bellamy, and Glass are the four narrators.  A mash-up of The Lord of the Flies, Across the Universe, and The Hunger Games this has already been turned into a  television series.

Shipstar

Science fiction masters Larry Niven (Ringworld) and Gregory Benford (Timescape) continue the thrilling adventure of a human expedition to another star system that is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure cupping a star, with a habitable area equivalent to many millions of Earths. And which, tantalizingly, is on a direct path heading toward the same system the human ship is to colonize.
