IT ALL COMES DOWN TO THIS.

ARE YOU AFRAID OF THE DARK?

The Cove has fallen. The woods are collapsing. Leonardo and the survivors return north to where their journey began, in search of allies to fight The Dark-a tangible nightmare in search of blood. But when they reach the Darkwoods, they find it even bleaker than they had feared. Any semblance of clan life has crumbled in the aftermath of the Dark.

Meanwhile, an ancient and bizarre game takes place high above the ground in the canopy of the Redwoods, a distant corner of the woods ruled by a leader who calls himself the general. Leonardo's party is magically whisked to their treetop world, where they face a race against time. The Redwoods kids care more about their rivalries than the impending Dark, and Leonardo is forced to join the game in an effort to dismantle it from the inside.

Every plan is dashed by a new setback, and the Dark draws closer by the day. Leonardo must outthink all of his enemies at once, or the woods-and all of its children-will vanish.
