Lily is 9. Her sister Daisy is 1. And she's no ordinary baby. Somehow, when she was born, something went rather wrong...and now Daisy is a Witch Baby. Nobody knows this but Lily - she's the only one who can see when Daisy makes the fridge float in the air, or turns people into slugs, or summons up her very stinky dog Waywoof...The sisters have just moved to a new neighbourhood, and their mum wants them to make friends. She decides to throw a party and send Lily and Daisy out to deliver the invitations. They meet some odd characters along the way...Will the party be a big success or will Daisy's magic mean things are even more chaotic than normal?
