'What a lot of island the river makes,' said Ida. 'We are on one, and I can see at least three others. We must go exploring and sail round them all.' And so begins a wonderful, magical summer. Ida, Oscar and Ping are staying with Ida's great-aunt at the ancient, river-encircled house of Green Knowe. But Great-Aunt Maud and her companion, Miss Bun, leave the children to do as they please - as long as they come in for meals! They set out to chart the river in the canoe and discover that it has surprising and mysterious secrets.
