I have gone with Salem's Lot. Very excited and already a few chapters in.. I chose SL as a break before I continue my journey to the Tower. I am very intrigued by Father Callahan (just finished Wolves of the Calla) and wanted to read more about his story before starting Songs of Susannah.
I'd suggest "It".
Different Seasons or The Bachman Books
I say this all the time . . .'Just Grab One~'
