Nicholas Benson is a university professor. The alien Katel is a Hunter, chasing an escaped criminal. The trouble is, she needs a body and Nick has the only one available. Now NIck has powers. He can do things he's always dreamed of doing as a boy. The trouble is, so can his enemies, and none of them appreciate being hunted. Nick's a Hunter now with a murdering mastermind to find.

Walker's on the run, definitely out of control and being pursued by her old boss. Nick's her only friend and he wants to help but this problem may be too big for either of them to solve. Kat and Meeta are running as well. There were too many left over questions from their last job and the Grand Council has decided they're not telling the whole story. So it's to the Vat with them to be recycled, a prospect both have decided to avoid. Right behind them is the best that HomeWorld has to send. Two soldiers whose job it is to bring everyone back for punishment and these guys never stop because they're not human. They don't need to rest and they're well motivated to succeed. Failure for them means a return to the prison pods they left. They'll do anything to prevent that. Kill anyone.
