That sounds like exactly the type of escapism that I need right now. Are the novels meant to be read in order? If not, do you have one or two that would be good to start with?
And while I personally enjoy the novels, I will say that some of them have not stood up to the test of time as well as others, and now read as very dated. Not discouraging you from reading them, just be forewarned!
The way to look at them is they are glimpses into Bond's past. A few of them are several stories, in fact.
That being said, the first published is also Bond's first mission so no harm in starting with Casino Royale either way.
