I go by author, personally. I have a nook, DH suprised me with it at christmas. My top fav. authors are: Laurell K. Hamilton, Beatrice Small, Mary Janice Davidson, Janet Chapman, Christen Feehan, Sherilyn Kenyon, Gena Showalter, and Lyndsay Sands. All have series and most have stand alone books to. I may have a book addiction on top of this quilting one....
