At long last reunited with his dad, Will now spends his days exploring the "land of the second sun," decoding the cryptic glyphs carved into its three mysterious temples--or eyeing the wild animals with renegade girl Elliott.

And the ruthless Rebeccas have once more cheated death. With a corps of cold-blooded Limiters at their command, they're determined to hunt Will to the bitter innards of the earth. This time, who WON'T escape with their life?
