There were many other books when I was younger like Goosebumps and Dr. Suess that sparked my interest in reading as well.
I’d also include The Bible though it defined me in another way other than literary fiction and non-fiction.
The Bible, and Unbroken
The Count of Monte Cristo, The Scarlet Pimpernel and Little House on the Prairie series. Favorite books of all time. Read them every year. Can’t really say they define me though. LoL
One of my Mom’s favorites.
God bless her.
1984 by George Orwell
The Lost City of Z by David Grann
Introduction to Nuclear Engineering by John Lamarsh
This made me think of the textbook that taught me about Electromagnetics and Maxwell’s equations as an undergraduate so many years ago. Ahhh… nostalgia… 
Robin Hood, the Bible, and Archie and Jugheads Comic Digest.
Three Poems, book by John Ashbery comes to mind.
Kinda like today’s Adele.
Speaks to everyone.
This is actually really difficult, so let’s just say these three are some of dozens.
Alice Adventure’s in Wonderland by Lewis Carroll (Of course.)
Coraline by Neil Gaiman.
We Have Always Lived in the Castle (or The Haunting of Hill House) by Shirley Jackson.
Alice in Wonderland was my first favorite book as a child, and of course, many schizophrenics including me find it relatable.
Coraline was my first Neil Gaiman book, and Neil was my favorite writer from age 11-15 and has influenced me massively.
Shirley Jackson was the first female horror writer I was exposed to, and she’s made me feel more confident being one myself, and the main characters of those particular books are very lonely and imaginative weirdos and thus very relatable to me. Merricat Blackwood in particular reminds me of myself, although I didn’t kill my family.
As a kid
The very hungry caterpillar
That book about the fish with the sparkly scales.
Red Riding hood
I’m watching the dirk gently show.
A Farewell To Arms
The Bible
Then there’s a book that I had when I was a kid that I really loved. It was from like 1954 and was about an old man who lived on a little island and something about his boat being lost and he found a new one after a hurricane. Loved that book, man 
Please discuss it in detail with me!!! What part are you on?
The Art of Loving by Erich Fromm,
Equality and Efficiency by ArthurM.Okun
Tao De Jing by Lao Zi
I read a LOT of fantasy books in my teens and early 20’s. They helped set my moral compass.
The Eye of the World - Robert Jordan
The Dragonbone Chair - Tad Williams

I don’t read books but I read my university books, human anatomy by Tortora, physiology, pathophysiology.
