It's time to move on.
Sally Wright has had enough of the Fifth Operational Corps to last a lifetime. She has been chased, kidnapped, and dogged by unknown horrors — and to top it all, the end of her engagement to Brigadier Alistair Lethbridge-Stewart has cast a shadow over her career. In an effort to leave it all behind, she requests a transfer back to the Regular Army... But, after everything she's seen, is it possible to return to normal life? And will the Brigadier let her go?
Harold Chorley cannot move on. While searching for answers to the missing gaps in his memory, he makes an alarming discovery; the Dominator war lord, Dominic Vaar, is no longer in prison. Hot on Vaar's trail, Chorley discovers an experimental military project that seems sinister in its appetite for volunteers. Volunteers who are never heard from again.
William Bishop is not looking forward to life at the Madhouse without Anne Travers, but in heading up a mission to Gloucestershire with Sally and Chorley, he soon finds other things to worry about.
One thing is for sure, not everybody will survive this encounter with the Dominators!
