Griffin and Fi continue on their quest to save all worlds from invasion in this fantastical follow-up to The Lighthouse between the Worlds, which School Library Journal called "a delicious tale of light and dark."

There is more than just one world?and all of them are in grave danger.

After a narrow escape from the battle-torn world of Somni, Griffin and his fierce, newfound ally Fi find themselves at the center of a war that threatens not only the people of Earth, but those of other worlds entirely. Connected by the lighthouse that acts as a portal, each world harbors a unique kind of magic that the greedy rulers of Somni are determined to capture for themselves.

Unless Griffin and Fi can find a way to stop these would-be conquerors, everything they hold dear will be lost. Navigating magical worlds of mist, water, vines, and fire in search of an answer, the two friends will have to discover their own gifts before they can save not only themselves but the worlds?every single one of them.
