A strange metal cylinder. A three-foot-tall bug-man. A dangerous world beneath the earth.

Eleven-year-old Harper Graybridge never expects that one junkyard discovery will launch him into an underground realm filled with bizarre creatures, ancient ruins, and secrets powerful enough to change his life forever.

When Harper meets Lyt—an insectoid traveler searching for the mysterious “keeper”—he’s offered the adventure he’s always dreamed of in the subterranean world of Murkmor. But Murkmor is far from safe. Poisonous jelly-monkeys stalk the forest, giant worms double as underground slides, and an evil overlord named Baron Vyndot believes Harper’s discovery is the key to unlocking a long-forgotten legend.

With the help of Lyt and a fierce bird-warrior named Crowll, Harper must navigate deadly tunnels, crumbling ruins, strange new allies, and a villain determined to control Murkmor’s most dangerous secrets.

Courage, friendship, and quick thinking may be the only things that can get him back home—alive.
