Maybe - Morris Gleitzman

It's 1946. The war is over and Europe lies in ruins. Fourteen year old Felix dreams of finding happiness elsewhere. When he's offered the chance to go to Australia, he seizes the opportunity. So does someone very dear to him, even though she wasn't actually invited. Felix and Anya have high hopes for a new life in Australia, but before they can accept the love and friendship of their new land they must confront the murderous urge for revenge that still hangs over them.
Felix knows he hasn't faced anything like this before. He may not survive, but he's hoping he will. Maybe.

This powerfully moving addition to Morris Gleitzman's bestselling series takes place in 1945, following directly on from the story told in Soon. This intensely affecting story will move readers of all ages. It will be welcomed by the many Holocaust educators who use Once and the sequels to teach upper primary and lower secondary children and embraced by any reader who loves passionate, moving and brilliant stories.
