Ben and Cassie have just moved into a new home, but it’s not quite what they expected as they have to share a room until the builders have finished doing it up. And Dad is very busy too.

Just working on the house while they wait for the tides to change? And is there really a bear living in the garden? Maybe they could catch him…
