When Pea Llewellyn's dizzy but dazzling single mum becomes Marina Cove, author of the bestselling Mermaid Girls books, everything changes. It's time to leave their tiny flat in Tenby for a proper house in London, and a whole new life. Pea likes the red front door, and the attic bedroom all to herself. She even likes her hideous new school uniform, in a masochistic Malory Towers sort of way. But there's an empty chair beside her in every lesson, and no one seems to want to fill it. In the absence of volunteers, Pea is going to have to acquire herself a best friend . . .

Eleven-year-old Pea and her wonderfully wacky family are back for their second adventure in this fabulously funny series. After securing herself a best friend and settling into London life, Pea is now contemplating her future and what exactly she should be when she grows up. Should she be a writer (like Mum)? An artist (like their crazy new au pair Klaudia)? A footballer? A pet therapist? Join Pea as she attempts to find out the answers - with hilarious results!

It's Pea's birthday, and all the family are gathered around to celebrate. But there's one person missing - her dad. She has never known him, but is the story Mum always told her (the one about Dad being a pirate) really true? What is this mysterious Piratical Father doing now? So begins Pea's quest to track down her dad once and for all . . .

Pea's family are separating for the summer holidays. Big sister, Clover, is off to Drama Camp, Mum is staying at home to finish her new book, and Pea and Tinkerbell are going camping. But things don't go quite to plan, and Pea finds her summer suddenly filled with Enid Blyton, castles, ghosts and mysteries . . .
