I have read and mostly enjoyed the Alex Delaware series by Jonathan Kellerman.
I have not yet read the last 2 books of that series yet (but I have those 2 and will read them later)

I have not read any his wife's books yet.

After constantly reading Alex Delaware since last spring (yes, that series took many months for me to go through) I felt I needed a break from Detective type stories so right now I'm reading a bit of thoughtless escapism...
Dean Koontz stuff.
I'll probably be reading that kind of book till at least after the Holidays.

Janet Evanovich was recommended to me, I have found some of them at Library free paperback exchange racks and the Goodwill but so far I have NOT read any of her books. Seems to be a series and my habit is to gather a series together so that I can read and follow the lives of the characters in proper order as written. The ones I've found are diff numbers of the series but I don't have #1 of her Plum series yet.
It's good to know the posters here enjoy her work.
