When Dad says that he's moving out, Lily-May feels all upside-down inside. But now Dad comes on Sundays, and they ride their bikes really fast and make secret dens together. Lily-May plays more just with Mum now, too - and when Mum's new partner Peter comes over, they play pirate ships! Sometimes, there are tricky moments - Lily-May hates it when Mum has to work late - but a birthday party with Lily-May's big fantastic family helps her realise just how many people love her.
