Book Series with Continuing Protagonists

Fromt he blog 'On Writing and Publishing' The author talks about the the Sookie Stackhouse and 'In death " series

These are hard to do. Mostly because the author gets tired of them or the reader does, and they are hard to keep fresh.

1) Sympathetic characters with enough depth in their pasts and personal problems in the present.

2) The characters clashes with each other, what underlying opposite philosophies will continue to clash and be explored.

3) A continuing arc (either personal in the Robb books or personal/plot in the Harris books).

4) Keeping the time period short.

5) Excellent secondary characters (though that might fall under number 1).

6) Heroes (male) that women want in their own lives.

7) The author still likes her characters and world.
