Alfie is crazy about space. His favourite things are: aliens, rockets, and 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...This is a positive, funny and charming take on the joys of a new sibling with gorgeous etched illustrations from a rising picture book star.
