Jessica is playing with her family at the river when she finds a dirty, bedraggled teddy bear in the water.

She has no idea that it will change everything, forever.

Meanwhile, Cymbeline comes home from school to find that his mum's house has been broken into - and the thieves seemed oddly focused on his toys. Thank goodness he had Not Mr Fluffy, his Bear of Most Extreme Importance, with him.

Soon, Jessica and Cymbeline find themselves swept up in a mystery that spans decades, threatens their families, and turns their lives upside down.
