The Hangman's Daughter by Oliver Pötzsch is a very good mystery. There are four books in the series.
I love the Game of Thrones books by George RR Martin. Mystery, drama, fantasy, it's all in there.
My favorite books I re read every so often are of course I think great:
The Jungle by Upton Sinclair
The Egg and I by Betty McDonald
The Good Earth by Pearl S Buck
The Camerons by Robert Crichton
The Ladies of Missalonghi by Colleen Mccullough
