Halo Novelization A Bestseller

According to Gamerfeed, the latest novel based on the Halo gameworld, called "Halo:The Flood", is a bestseller, cranking it up close to the Top 10 in the 'mass market paperback' category. Do people think that game novelisations, as discussed in this USA Today report, can be worth reading? Marc Laidlaw's CD-ROM novelization, Gadget: The Third Force, is at least one game-related novel I enjoyed a lot.
