I like books with repeat characters on a realist timeline. It is cool to read a character written over 20 years, just to hear about changes in technology over the years - especially in detective stories like I read mostly.
So here is MY favorite SERIES, I do it on Audiobook, read by Jack Reacher. But the author Lee Child is brilliant!
This is the best SERIES I have ever read, by Lee Child, follow the adventures of Ex-Military Trained Jack Reacher, a nomad of sorts, keeping an invisible footprint - he's off the radar. Kidnapping, ransoms, powerful story lines.
Read on Audiobook by Dick Hill (the best reader alive - multiple award winning reader) dick IS Jack Reacher to audiobook fans.
This is worth EVERY PAGE you turn.
