The story opens in 1939, as Kate Sheridan leaves her home and strict parents in rural Ireland to live with her aunt and uncle in London. This move allows Kate an element of freedom she has never had before, but England is on the cusp of war and London is no longer a safe haven. When Kate meets the devilishly handsome Flight Lieutenant Charlie Butler during an air raid, the course of both their lives is changed forever. What then follows is a story which follows the lives of both Kate and Charlie during the course of the war. They face many difficulties, and their love affair is subject to, not just the challenge of separation, but also bears the burden of parental disapproval and the heartbreak of loss on a grand scale.
Into the Unknown is a sympathetic look at the uncertainty of life during the Second World War. The characters are believable; I found both Kate and Charlie to be worthy protagonists and enjoyed watching their characters grow in maturity as the novel progressed. Their individual wartime experiences are sensitively explored and their thoughts and feelings are both realistic and thought provoking.
I really enjoyed the story and was absorbed from the beginning in the way Kate and Charlie's lives progressed. I genuinely cared about what happened to them and testament to the author’s skill at storytelling, I read the book almost in one sitting, as I wanted to find out how the story progressed.
