If there's one thing that should be done well, it's books based on videogames. Gamers place ridiculous standards on their favorite properties, so there's really no excuse for publishers to do a half-assed job when making any additional product for the franchise. It doesn't matter if it's another game, action figures, posters, or even books. Though the latter is a rarity, Splinter Cell is one of the few franchises that has continued to put out fairly decent literature, even by a gamer's standards.
Their latest isn't worth the paper it's written on.
