I put together this list to share a wide range of books that you might not have tried yet. Some are well known classics, others are lesser known, but all of them offer something memorable.

My goal isn't to only include obscure titles, but to recommend some well acclaimed books too that are genuinely worth trying across different genres.

If you think something fits better in another category or have recommendations to add, feel free to share them. I can add them to the list. I know you can just Google up and find new books but I had an irresistible urge to make this.

Important Note: The "Also Try" sections aren't honorable mentions. They are there because after finishing each category, I kept thinking of more books, and it would have been a pain in the ass to re-number the entire list, so I made that section for that. The books aren't ranked in any order.
