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.
These are some of my favorites sorry if there not really your thing but i think each of them is great Halo: Fall of Reach (Military Sci Fi) The Hobbit ( Fantasy) Killing Floor (Mystery Thriller) Great book 👌🏼 The Martian (Sci Fi) Makes the movie look silly Under the Dome (Thriller) This one because you say you like stories and its super enjoyable to read all the different characters stories... my favorite book I've read so far this year and im on book 16 this year... but its a long one 1000+ pages
For me the best books in the English language I've read recently are The Picture Of Dorian Gray by Oscar Wilde, The Ocean At The End Of The Lane by Neil Gaiman, The Bane Chronicles by Cassandra Clare, The Great Gatsby by F Scott Fitzgerald & the Song Of Ice And Fire series by George R R Martin. They are all incredibly well written but in the end it also depends on your personal taste, I love the fantasy/horror genre a lot because the stories take you to entirely different worlds.
