Query: An initially engrossing novel that manages to fall flat

Now and then I pick up a book solely based the the cover. I had never heard of the author but upon reading the blurb it sounded like something similar to McCammon's Swan Song, one of my favorite novels of all time. The story is initially very ambitious, introducing many characters and plot lines. But it seems that just when you are really getting into the characters, it suddenly hits you that there are only a hundred or so pages left in the book. It's like when you are watching a show on television and you suddenly realize that there are only five minutes left and they still haven't got Timmy out of the well... Needless to say, the ending feels rushed and is very unsatisfying. Better "end of the world" novels would include Niven and Pournelle's "Lucifer's Hammer", King's "The Stand", and McCammon's "Swan Song".
