Secret Coders by Gene Luen Yang
My rating: 4 of 5 stars
Yang's graphic novels are always fun to read (even for people like me, who don't do well with this genre). Here he seems to be going for a younger audience than in Boxers/Saints or American Born Chinese. The introduction to binary as a code is really well done but the abrupt ending was a little problematic. Until the second book in the series is out this may not catch on as a result.
