The Clockwork Key

While visiting a relic-hunting relative, two white-cued siblings find themselves embarking on a fantastical quest in this freewheeling steampunk romp from Hardy (The Weather Well) and Sheerin. Brother-sister duo Mabel and Will Graystone are excited to spend the summer with their daring explorer aunt Lucy and her talking cat stuffie, Grimm, which she found years ago during a dig. Their goal is to travel to the faraway continent of Marvolia and uncover the whereabouts of the lost city of Umber, which was seemingly abandoned overnight. But they aren’t the only ones on the trail: rival relic hunter Byron Cogsworth is hot on their heels. Guided by an old map and a mysterious key, the group locate the hidden city, and when Mabel and Grimm wander off alone, they stumble upon a secret palace—and inside, a human-size princess doll. Winding the doll with the key brings her to life, inadvertently awakening an ancient magic that threatens to trap Mabel and her family in Umber forever. Dynamic prose skillfully balances suspense, humor, and family dynamics, keeping readers on the edge of their seats as the children navigate both treasure hunts and magical mishaps. Animated grayscale illustrations with retro finishes amplify the fantasy elements. The result is a jaunty adventure that’s ideal for fans of imaginative, family-centered hijinks. Ages 8–12. (July)
