What would it be like to walk into your living room one day and meet a complete stranger who says she’s your mother? It happens to Dizzy on her twelfth birthday. Storm ("Please don’t call me mum!") arrives, and the nice, safe, predictable life Dizzy has made with her father is blown to bits. Storm convinces Dizzy to go away on a short holiday with her—something she says Dizzy’s father has agreed to—and so begins a wild, van-traveling, musicmaking, teepee-sleeping, patchouli-wearing summer! But soon enough the fun wears off, and Dizzy begins to realize that Storm is not the mother Dizzy always dreamed she’d be.
