Andrew J. Offutt’s 1973 The Galactic Rejects is a standalone SF novel.
The starship Brunner, having been ambushed by the alien Azuli, is doomed. The crew of the Brunner, hoping to prevent panic, assure their passengers that there enough spacepods for all. This is a lie, but it doesn’t convince the telepath Rinegar. He commandeers a spacepod and escapes.
The spacepod lands on the nearest world, which just happens to be conveniently habitable. The pod can’t take off again; Rinegar is marooned. With him are two strangers, fellow veterans of the Terran-Azuli war: flighty teen Corisande and twenty-something delinquent Berneson.
