When I get involved in a long book like The Historian, I have trouble reading a new book. I've been in that world for so long that it almost seems real to me; it feels like leaving my own life to read another book. The only cure for this, I've found, is to read a book that's a quick read -- usually something funny, but not necessarily so. Robert Parker's Spenser books usually do it for me but I think I've read them all. Any suggestions?
