Query: Great First Half - Hazy Finish

R.J. Pinero caught my attention with Y2K. I really enjoyed the "down-to-earth" way he crafted a technology based concept into a really good book.So, I bought 01-01-00 with high expectations.At first, perhaps because I'm in the network security business and actually know one of the key characters, I was intrigued, even a bit excited. It really promised to be a great read.Even when he began to inject the Mayan angle I was fascinated. Hey..."Chariots of the Gods" made the premise almost believable.However, I suspect he just got tired of writing and took the easy way out with a surreal ending that left me cold. Too bad. He really has a knack.O.K. R.J...let's see what you've got!
