Maybe (Once/Now/Then/After) / Gleitzman, Morris

1946. Europe is in ruins. Millions dream of finding happiness somewhere else, and 14 year-old Felix is one of them. When he's offered a journey to somewhere far away, he seizes the opportunity. So does someone very dear to him, even though she wasn't actually invited. They have high hopes for their new land. But before Felix and Anya can embrace the love and friendship of their new world, they must confront the murderous urge for revenge still alive in the old. Felix knows he hasn't faced anything like this before. He may not survive, but he's hoping he will. Maybe.
