Bobble knows that her father is suffering with shell-shock since he fought during WWI, and the constant planes flying over the house are triggering him, which means it's up to her to help her mum in the house as well as with her dad. The war changed children's childhoods and forced them to grow up quickly, and If The Invader Comes shows this. Once they discover that their parents are involved in dangerous and top-secret war work, Bobble, Cilla and Cadan step-up to help them, and this is often dangerous in more ways than one. The trio are brave and wonderful characters who reader will very much enjoy getting to know.
The book brilliantly portrays the reality of war for children and the dangers it posed. As characters they are very different: Bobble is brave and empathetic, showing her understanding of what others are going through. Cadan is clever and calm in the face of danger, especially whilst commanding the Iris; whilst Cilla is strong and determined, and refuses to conform to expectations, especially when it comes to flying planes. Together, they are a force to be reckoned with and, despite the book being shorter (198 pages), they are perfectly formed.
The plot is well-paced and looks sensitively at themes that will engage readers whilst keeping them gripped as they feel like they are alongside Bobble and her friends. If The Invader Comes is a book perfect for those studying WWII or anybody who enjoys a good adventure, and I'd really love to know what's going to happen to Bobble and her friends next.
