“The Secret of the Catapus is an extraordinary story of love: for the natural world, for standing up for what is right, and for carrying forward a grandparent’s legacy. Ellie is a force, and the town of Whitneyport hums with Down East traditions as it confronts our desperate need for greater ecological responsibility. You’ll have to listen to these whip-smart kids, and you won’t want to leave these waters.”
—Gregory Brown, author of The Lowering Days
