Griffin and his father tend to their lighthouse on the craggy coast of Oregon with the same careful routine each day. There are hardly ever any visitors, but they like it that way. Which is why, when a group of oddly dressed strangers suddenly appears, Griffin begins to see just how many secrets his father has been keeping. He never imagined that his lighthouse contains a portal to strange and dangerous worlds, or that a Society of Lighthouse Keepers exists to protect the Earth from a fearsome enemy invasion. But then Griffin’s dad is pulled through the lens of the lighthouse into one of those other worlds. With his father gone, nobody from the Society is giving Griffin any answers, so he’s on his own. Armed only with a book of mysterious notes from his parents, Griffin is determined to find his dad, no matter what dangers lurk on the other side of the portal.

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 Kirkus Reviews called “a fast read that ends too soon.” 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.
