Frankenstein and 1984 would be good places to start!
Ooo Jane Austen and Agatha Christie are great starting authors in my opinion (also the subject matter isn’t so depressing compared to some others), 1984, To Kill A Mockingbird, Of Mice and Men, Great Gatsby and Handmaids Tale are much more modern classics so those might be a bit easier to read as well (they are also regularly read in high schools and colleges, so there are lots of papers on them, Frankenstein is also an great read (tho it’s a bit more confusing and significantly more depressing)
Huckleberry Finn, Great Expectations
Others, but I’m not sure if they’re easy, per se:
A Tale of Two Cities
The Count of Montecristo
Little women by Louisa May Alcott
Classic to the core, it's very light and about daily lives of 4 sisters in 18th century
i'll second Great Gatsby and add The Catcher in the Rye! both are easy enough to get into and interesting
Absolutely wrong place to ask this but any classical novel recommendations that are easy to get into/beginner friendly? Thanks
