Based on the blockbuster podcast where the McElroy brothers and their dad play a tabletop RPG and illustrated by cartooning powerhouse Carey Pietsch, The Adventure Zone: The Crystal Kingdom takes this #1 New York Times bestselling series to haunting new heights.
A desperate call for help interrupts holiday celebrations at the Bureau of Balance, and sends Taako, Magnus and Merle on a high-stakes mission to find and Reclaim a fourth deadly relic: a powerful transmutation stone, hidden somewhere in the depths of a floating arcane laboratory that's home to the Doctors Maureen and Lucas Miller. An unknown menace has seized control of the stone, and is using it to transform the lab into a virulent pink crystal that spreads to everything it touches. It's only a matter of time before this sparkling disaster crash-lands, but in order to find the stone and save the whole planet from being King Midased, our heroes will have to fight their way through a gauntlet of rowdy robots and crystal golems, decide whether they can trust the evasive Lucas Miller, and solve the mystery of what--or who--has put them all in peril, before there's no world left to save.
