My World "Series" of Books

I read Painted Ladies, the last book of the Spenser series, written by Robert B. Parker before his death. I enjoyed the book, the characters and I'll miss the Spenser series. It led me to consider a list of the best series of action-adventure books that I enjoyed. Listed below are series that I enjoyed in the past and today:

1. The James Bond Series by Ian Fleming, Raymond Benson, Sebastian Faulks and Kingsley Amis
2. John Rain series by Barry Eisler
3. Virgil Cole and Everett Hitch westerns by Robert B. Parker
4. Hardy Boys by Franklin W. Dixon 
5. Jack Reacher series by Lee Child
6. Lucas Davenport series by John Sandford
