After being magically transported to another world with two other high
school students, perennial outsider Billy Smith has become the unlikely
king of a goblin civilization. With the help of his
first-day-of-high-school crush, Lexi Aquino, now a powerful wizard,
quarterback-turned-warrior Kurt Novac, and a cowardly but wily goblin
named Hop, Billy has successfully repelled a human invasion of the
goblins' underground city, Kiranok. But the leader of the attacking
Hanorian Army, Lord Marshal Jiyal, has returned to the Hanorian capital,
Gran Hanor, where he's preparing for a second invasion.
Billy decides the only way to end the war is to neutralize Jiyal's
powerful ally, a young wizard named Mig. Billy and Kurt set off for Gran
Hanor to find Mig and trick her into drinking a potion called the Final
Drop that will nullify her magic forever. But after their departure, the
Dark Lady, the mad elven wizard who started the war, reappears in
Kiranok and reclaims her place as the goblins' leader. She coerces Lexi,
who's struggling with madness from using too much magic, into helping
her raise a skeletal army, then she and her Marching Dead force the
goblins to march on Gran Hanor.
Now, Billy must find a way to stop the Dark Lady and her skeletal army,
neutralize Mig, help Lexi regain her sanity, save the goblins, and make
peace with the Hanorians before a cataclysmic final battle destroys them
all.
