Two, two, two books in one! The blue side ("Heroes United") is an overview of the DC Super Friends toy line characters (Batman, Aquaman, Superman, Green Lantern, and the Flash). The flip side ("Attack of the Robot") does a good job of introducing basic conflict into the SuperFriends universe, with Lex Luthor inventing a giant robot with a kryptonite hand to menace Superman. The thing is, he's not just fighting Supes, he's fighting the whole team and teamwork always wins. Good morals, art in the style of the toy line, and a nice streamlined story. Bonus points for the little stand-up figures in the middle of the book for solo play. I recommend lamination for those bad boys--they're kind of flimsy. The only bad thing is the boys club mentality; despite DC Comics' push for the "Trinity" of Batman, Superman, and Wonder Woman, the Amazon is nowhere to be found. I hope she shows up soon--my son actually complained.
