Meet eleven-year-old Pea and her definitely not ordinary life . . . When Pea'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.

In the absence of volunteers, Pea is going to have to acquire herself a best friend . . .
