Walker's gone wild. Something has fractured inside and her beast is lose. She can't control it anymore and her old boss is after her. 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 are trying desperately to avoid. Right behind them is the best that HomeWorld has to send; two soldiers built to hunt the hunters. Their job is to bring everyone back for punishment and these guys never stop because they're not human. Not anymore. 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.
