War has been declared. Men and Women from all over Britain are being conscripted. Krista and Perry are in the thick of it. Krista and her fellow Special Service Wrens are much in demand. There are no rules in place for what is demanded of them - they must just get on with the job at hand to the best of their abilities.
Krista is challenged like never before. She must find ways to accomplish what is asked of her. Who knew when she left France that she would be called upon to help in the protection of Britain? But it doesn't matter now. She is in it for the duration. She will succeed or fail on her own merit. She is not alone: every citizen of Britain will be involved in the fight to survive.
