This trilogy , fictionalised as it is, is really Judith Kerr's own story of her family's escape from Nazi Germany at the time of Hitler's accession to power, their stay in Switzerland and then England, deprived of the comfortable lifestyle they had in Berlin (her father was a successful and highly esteemed writer), her first steps in the world of creative art (and a parallel love affair) and then, in her third book, her return in the 1950s to Berlin to visit her ill mother. It is written very simply and directly, as for a young person, but there is nothing childish about it. The directness makes it both powerful and moving. I have never read such a 'real' personal account of the Blitz, for example. I came to these books through the writer's children's books about The Tiger Who Came to Tea and Mog the Forgetful Cat, classics both. These three books are a different kind of thing, but it is easy to see the link between the gentle humanity of the children's books and this trilogy. Strongly recommended.
