This is like that. Silly? Sure. Fun. Oh yeah. Lot's of fun. I also enjoyed the alternate universe aspect of this one with Easter eggs and and cross pollination of characters from many other Keene books. It reads like a present to his fans and since I am one, I enjoyed it.
Not one of Keene's or Gonzalez's serious books, this one is played for the fun of it, and if you think you will enjoy it, then you probably will. Not a serious part of the canon of either writer but fun nonetheless.
This is a Saturday Matinee of a book.
