Here's a pretty long and varied list: The Harry Potter series, the Percy Jackson and the Olympians series, Ready Player One, To Kill A Mockingbird, and The Great Gatsby. I am excited to start reading some more Shakespeare.
I enjoyed reading the Chronicles of Narnia. It was given to me as a box set on my birthday by my girlfriend. I just wish C.S. Lewis would still be alive and publish more books about the world of Narnia. The way he created the world of Narnia is quite beautiful.
Travels with Charlie by Steinbeck - book, Rime of the Ancient Mariner by Coleridge - long poem ( 13 pages at least ), Anything by H.P. Lovecraft, If you like Harry Potter not the same but I recommend the Fablehaven series by Brandon Mull
My personal favorite was a book that's considered an autobiography of Swiss psychologist Carl Gustav Jung. It's called "Memories, Dreams, Reflections". The book is over 500 pages long in my native language but I read it in 3 days. Jung is known for such ideas like Collective Unconscious, Archetypes, he introduced concepts like extroversion and introversion. He is known for having a profound interest in religion, mythology, and even the occult. He saw these ancient traditions and their practices as a symbolic expression of things like psychological development and the structure of the unconscious mind.
