Most Helpful Girl
Frankenstein is my all-time favorite, though you have probably read it, depending on what country you are from. In the USA it is one of those books that are pretty popular to read in high school English class.
The book I have read the most times, is Interview with the Vampire by Anne Rice. I just love her style and the work she puts into being historically accurate in her works of fiction is just awesome.
The Burn Journals by Brent Runyon. It is a memoir about a guy who doused his robe in gasoline, put it on and set it on fire when he was 14. Burned 85% of his body. It's about his journey to recovery. Really interesting read.
The Amityville Horror by Jay Anson. I know everyone has probably seen the movie. The movies didn't scare me as much as the book. The book gave me nightmares and many sleepless nights.
The Cleft by Doris Lessing. About a society free of men. Pretty damn creepy, though I am not sure it was meant to be creepy.
