The Lion King meets Wings of Fire in the magical rainforest kingdom of Caldera in this new middle grade animal fantasy series from New York Times bestselling author and National Book Award finalist Eliot Schrefer.

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 means Mez must leave her sister behind and unite an unlikely group of animal friends to unravel an ancient mystery and protect their rainforest home.
