Anyone who has hiked through time knows the town of Pocket. It’s the place time travellers first reach after they stumble away from their hometime, passing through on their way to any other when.

To Calisto, Pocket is home. They love their grandmother’s shop, which is filled with clothes from every era that are used to make costumes for time travellers. Calisto has no intention of travelling – it’s too dangerous.

For Fawkes, travelling is life. He put on time boots when he was young and has been stumbling through eras ever since. When he floats into Pocket, Calisto meets him for the first time, though Fawkes has seen Calisto before – in glimpses of what hasn’t happened yet.

He’s also seen the villains chasing them both. Now Calisto and Fawkes must rush – from Shakespeare’s London to ancient Crete to California on the eve of a millennium – to save Pocket, and all those who travel, from being erased.
