Reading Series

This may be challenging to see, but this is my reading series challenge. About a year and a half or two years ago I made myself a goal to read through several series of books all written by the same author. I've made some good progress, but boy do I still have a long way to go. 

These aren't the only books I've read. I just finished an "off series" book, and actually, I'd bet it's about 3 to 1. For every 4 books I read, 3 are from the series. Some of these are commitment books. I just finished Rainbow 6, and that sucker is long. 

Additionally, I remember reading that as a kiddo, in college. I loved it then, like Debt of Honor. Now, reading them, I'm not impressed. Not impressed at all. 

Still it's a fun goal, and keeps me on track. Right now, it's Odessa File and after that Lion's game.

The problem? I'm thinking of adding more series, especially now that I've finished one entire series.
