The second book in New York Times bestselling author and National Book Award finalist Eliot Schrefer’s Lost Rainforest series teems with thrilling action, playful humor, and a vibrant animal cast as the shadowwalkers battle to save their magical rainforest home.

Caldera always existed in harmony between the creatures who walk by day and those who walk by night—until the Ant Queen awakened. Now, in the year since the shadowwalkers’ narrow escape, the ants’ destruction has only spread. So when Gogi, a shadowwalker monkey still learning to wield his fire powers without burning his tail, discovers that the nearby forest has been leveled, he knows it’s time to act.

Reunited with his shadowwalker friends—including a healing bat, an invisible panther, and a tree frog with the ability to control the winds—Gogi embarks on a quest for a powerful object that can harness the magic of the eclipse. But their only hope of stopping the Ant Queen is secreted away at the edge of Caldera. And with just weeks before the next eclipse, Gogi must race to prove that he can control the mighty depths of his talent if he is to protect his friends, save the rainforest, and return home unsinged.
