The magical rainforest of Caldera has forever been divided into those animals who walk by night and those who walk by day. Nightwalker panthers, like young Mez and her beloved sister, have always feared daywalkers as creatures of myth and legend. Until the eclipse.

Now Mez has discovered that she can cross the Veil and enter the daylight world. Her magical power has unknown depths, but she must rush to discover it after a mysterious stranger arrives at her family’s den, bearing warnings of a reawakened evil. Saving Caldera might mean leaving her sister—and everything else she has ever known—behind.

Award-winning and bestselling author Eliot Schrefer has spun an exciting fantasy adventure about unlikely animal friends—including a courageous bat, a scholarly tree frog, and an anxious monkey—who must unite to unravel an ancient mystery and save their rainforest home before it is too late.
