I'm Dan Hope and inside my head I keep a list of things I want to come true. For example, I want my sister to go to university at the North Pole and only come back once a year. I want to help Sherlock Holmes solve his most daring mystery yet. I want to be the first eleven-year-old to land on the moon. And finally I want my dad to love me.
Becket Rumsey is all at sea. His dad has run away with him and his brother, Billy, in the middle of the night. And they've left everything behind, including their almost-mum, Pearl. Becket has no idea what's going on - it's a mystery. So with the help of Billy and a snail called Brian, Becket sets out on a journey of discovery. It's not plain sailing, but then what journeys ever are?
