If you have not yet read “Night of the Purple Moon,” read it now. And then read this (2nd) title in the Toucan Trilogy by Scott Cramer. In book one, the youth of the world have to make hard decisions on how to survive w/o adults and in book 2 (Colony East) the kids are hit with a 2nd illness and the challenges provided by surviving with the adults who remain. These stories are interesting, intense and thought provoking. I am currently midway through “Generation M,” the 3rd and final title. I highly recommend all three books and encourage anyone to read them, regardless of your usual reading interests.
