Query: What an Intense Trip!

First off I want to say that John Gilstrap has some of the best characterization I have read in awhile. Nathan's Run takes place over a two-day span of time. Mr. Gilstrap does not waste any of this time on fluff. The author uses his pages wisely to develop realist characters and plot. The villains are especially nasty and the heroes are flawed but very likable, good solid heroes. Mr. Gilstrap does a great job in weaving these characters into a very believable and real plot. There are only two things that I'm sad about, one that I didn't read this book sooner and that it ended. I really wanted it to continue for a few more chapters, but the book is called "Nathan's Run". So if you are looking for a good chase book with good characterization and plot, you won't go wrong with "Nathan's Run". This is a wonderful book; I look forward to reading more of John Gilstrap.
