This has got to be my favorite of the Theo books so far! I loved seeing him take on environmental and political issues. It's like, GO YOU YOU FUNKY LIL ACTIVIST! It's exciting. The masks, the video, everything! Each Theo Boone book tackles a complex issue in such a way that it's understandable for young kids, but Grisham ALSO does not sugar-coat anything, and this skillful balance is to be commended.
