Douglas Adams - if you liked the Hitchhiker’s Trilogy, check out his other books: Long Dark Tea-Time of the Soul was great(IIRC, haven’t read it since HS, but plan on finding it again)
Nam Novel-
A Reckoning for Kings by Chris Bunch and Alan Cole…I was obsessed with Nam during JH and HS, and this was the best novel in that genre I have read
Point of Impact by Stephen Hunter…first book in a series, great book
Reagan’s War by Peter Schweizer
The One that Got Away was a great read, Chris even goes into his PTSD after the escape. It is related to Bravo Two Zero, written by the patrol leader Andy McNab. The two books disagree a bit on certain details, but if you want to find out what happened to the rest of the patrol after Chris got separated from them, Bravo Two Zero is a good addition. McNab also started writing fiction a few years ago, and has a whole series of novels written in the first person that are entertaining.
Inside Delta Force by Eric Haney… Haney was one of the first men selected to Delta, and this is his autobiography. Interesting stuff about the actual selection process they used back then, some of which is still in use today.
Catch-22 was great, I didn’t see what all the fuss over Catcher in the Rye was about(okay book but I didn’t understand the controversy).
If you enjoyed DaVInci Code, check out The Hiram Key by Christopher Knight and Robert Lomas. Interesting stuff.
None Dare Call it Conspiracy by Gary Allen, google it, it is on line now.
Rule By Secrecy by Jim Marr was interesting, though he drew some really far out conclusions at the end. That is what kept me from reading any of his other books.
