The Pixels, Journey to the Bottom of the Desk

Global warming has wrecked havoc upon Upper Poyntz Colony. The Pixel Corps of Discovery--Speck, Dotty, Nano, Bitty, and Grandpa Grain Pixel--is sent out to find the source of the excess CO2 in the atmosphere. Days later, the Pixel's plane crash lands in a strange world, on the desktop of fourth-grader Faith Singer. Being one millimeter tall, the Pixel family must take a long, perilous journey to escape--through the inside of the desk and out the bottom.
