It is true though that after you have read several of his books, they all begin to feel oddly similar and familiar. That is OK. It is kind of like rereading the same book (something I will do with a particular favorite), but with some extra variety. I try to read one of these every now and then. About when I can't remember for sure the name of the last book I read, it might be time to read another. Reading several of his books back to back, would be mind-numbing, something akin to chain smoking.
Years ago at a yard sale, someone was selling a whole collection of his books, probably for $1.00 each. I made an offer for the whole bunch and took them all home. I dig through the box and try to pick one out that I am pretty sure I have not read already.
Here is my list of books written by Louis L'Amour.
