'After the Apocalypse, Ven the android is sent away with the last surviving human child. Almost a century before, a scientist named Arvel Hem speculated that humans suffer from a “chronogenetic species-wide pathology” that has now caused mass die-offs. The boy named Solomon may be the exception. There may be others. Ven’s quest is to find Hem, who took off across the universe to avoid the conflagration he knew was coming to Earth. On the ship, Sol grows up, Ven slowly deteriorates, and so does their vessel' (Lois Tilton, Locus Online).
