The Pirate Mums by Jodie Lancet-Grant

Billy's family is not what you'd call ordinary. His mums won't listen to NORMAL music. They love to sing sea shanties and dance jigs in the lounge. Their clothes are highly unusual, they have a rude parrot for a pet, and their taste in house design is, well ... FISHY.

Billy wishes his family could be more like everyone else's. Until a swashbuckling adventure changes everything!
