Magic by the Lake

The further adventures of Martha, Jane, Mark, and Katharine, from Half-Magic. Their summer vacation is enlivened by an entire magic lake, channeled through a talking, and somewhat grumpy, box turtle. They are stranded on a desert island, visit Ali-Baba's cave, and end up rescued-- by some children the reader sees in the next book. Half Magic and Magic by the Lake are set in the 1920s, much earlier than the other Tales. They draw on Eager's own childhood in that period, including vacations at Hamilton Lake in northern Indiana (the setting for Magic by the Lake).--Wikipedia (accessed 12 August 2024).
