Alfie is crazy about space. His favourite things are- 1. aliens, 2. rockets, 3. the moon - in that exact order. He doesn't really think much about anything else, until his new baby sister comes along. Then he notices that she looks a bit funny, she talks funny and sometimes she smells funny and he realizes . . . she MUST BE AN ALIEN! Alfie knows he needs to be brave and take her back to the moon where she belongs - after all, she often cries for home - and that's when the adventure really starts. . . A positive, funny and charming take on the joys of a new sibling with gorgeous etched illustrations from a rising picture book star.
