Poor Lenny Levi has no luck. First there is WWII. His father goes off to fight. London is bombed and Lenny is sent to stay in the country with people who didn't want a boy. The other kids are mean to him. He starts wetting the bed. His mother's letters stop coming. His only consolations are a statue of a unicorn in the garden and rare talks with a soldier who has lost his leg.
Parents may want to read this first to make sure it is not too sad or upsetting for their kids.
