First off, to anyone reading this review, the author is upset that I gave one of his books a bad review. This is his idea of revenge.

Second, I've had people mention that before and it's very easy to explain. As Doc Brown would say, You have to think 4 dimensionally. To put it simply Frost isn't telling the story NOW. Think of it as Frost is an old man writing his memoirs. This allows him to add more information he would not have known at the time but learned about later. When I changed it from third to first I didn't just change the pronouns; I rewrote the novel entirely, so it was not because I just plumb forgot how to write in first-person. I suppose it would have been smart of me to put a prologue in to explain when exactly Frost is writing this for people who simply can't get that concept otherwise and make all sorts of silly accusations.

I'm sure you're wrong about it shifting from past to present tense. I haven't read it in a while, but I flipped through my paperback copy. If you want to actually point out some of these shifts I'll look it up.
