After a reckless, anger-fueled act, Jim Lake, Jr., sets out on his own in a strange new world: the Darklands. Separated from his friends back home, Jim is discovering exactly what it takes to survive in this new realm as he encounters a whole new horde of Trolls. Back in Arcadia, Toby, Claire, and Blinky are doing their best to get by--and maybe, just maybe--find a way to reunite with Jim.
