From this precarious vantage point, I can see the shape of the whole arena for the first time. A perfect circle. With a perfect wheel in the middle. The sky above the circumference of the jungle is tinged a uniform pink. And I think I can make out one or two of those wavy squares, chinks in the armor, Wiress and Beetee called them, because they reveal what was meant to be hidden and therefore a weakness. Just to make absolutely sure, I shoot an arrow into the empty space above the tree line. There’s a spurt of light, a flash of real blue sky, and the arrow’s thrown back into the jungle.
