Discordia: The Eleventh Dimension (by Dena K. Salmon)

This is the children's lit equivalent of a B movie. The story doesn't make much sense, the characters are cardboard, and the gore is mostly gratuitous, but it's enjoyable enough in a cheesy sort of way. One can imagine it done with cheap sets and visible zippers on the costumes. It has its share of scares (though not as scary as you might expect) and cliffhangers (including the ending), and passes the time agreeably if you or your kids are into this sort of thing.

Early on there are long stretches of transcriptions of video game play, which will be entertaining for kids who love this type of video game, and not so much for anyone else. Once Lance and MrsKeller have entered the world of Discordia for real, it still reads like a video game, as presumably it was intended to. So ... not great, not terrible, a bit of gratuitous gore but otherwise mostly harmless. This is one of those books that some kids will love, and if they are not normally avid readers, their parents and teachers will sigh and say, "Well, as long as they're reading ..."
