But now Zoanna and Rowforth have joined forces to take revenge on Kelvin -- and they intend to have it through his unborn child. Kelvin's beloved Heln lies helpless in the prison Zoanna and Rowforth have built for her, while Kelvin is trapped in a distant Frame World, a captive of the dread Chimaera.
