Mad_Cyril one of the best reading experiences I ever had was when I first read it at 13 years old I remember coming to the point about 100 pages in when you suddenly realize it was about vampires. The Finnish first edition translation I was reading was designed like the first US editions so you didn’t know it. Later copies just put vampires on the cover. My current copy, an English language paperback sure does.
I’ve reread it many times since at always enjoyed it. Stephen King really perfected his small Maine-town bit already on his second published novel. On first read you want the plot to move on and not spend time with the people of the town, but once the killing starts it really pays off.
