The Bourne trilogy is indeed far superior as books - the films really do not do them justice. Just a word of warning though - make sure if you buy them as seperate books that you read them in the order they were written. They will make no real sense and have huge spoilers in if you read them out of order.
The original trilogy was written by Robert Ludlum. I read an article/review which stated that the others on bourne were written in collaboration with RL, not by RL, and that they were not a patch on the original trilogy. I have not read any other than the original trilogy, so pass that on for info rather than opinion.
As for other books, I am currently reading through Michael Connelly (US LAPD detective series) and the Jack Reacher novels by Lee Child. Have also dipped into Tom Holt this year but find him a bit hit and miss. Terry Pratchett is always a great fallback, as is Ian Rankin and Rebus, although that series is now finished - his latest book due in Sept is on an art theft - looking forward to that, seeing how he handles crime from the other side of the fence so to speak.
With holiday reading I always take a trusted backup - nothing worse that being stuck on a beach with a book that is pants and no way to change it!
