Liverpool, 1910. When Patch runs up the gangway of the steamship, RMS Glorious, she isn't planning to hang around. But if she leaves her hiding place, the constable might catch her, so sitting tight is worth the risk. Her plan is spoiled when she realises too late that the ship is setting sail, and Patch finds herself an accidental stowaway. Luckily, Patch's unconventional past has made her pretty fearless when it comes to fending for herself, and besides there are friends in high and low places to be made onboard. But hiding away becomes less and less easy - her new friends urgently need her help and there's a mystery that needs solving, all before they reach New York.
