Dracula!
I finished Main Street. It moved pretty slowly for the first 3/4 of the book, but the end engaged me. Still, The Grapes of Wrath proved a difficult act to follow.
I've now moved on to Dracula. I started reading it last night while I was home alone for a while, and it was dark outside, and the house creaked (it turned out to be the cat in the rocking chair). I think I'll limit myself to reading this one only during daylight hours!
