I have read a few.
Frankenstein was good.
Dracula, written as a journal, was hard to read, but the terror was apparent.
Ben Hur spent the first half of the novel (300-pages) on the three wise men meeting in the desert. A very dry read, IMO.
I’ve also read:
The Time Machine
Treasure Island
Moby Dick
20,000 Leagues Under the Sea
Doctor Jekyll and Mr Hyde
The Invisible Man
The Mummy!
A Christmas Carol
The War of the Worlds
The Legend of Sleepy Hollow & Other Stories
A Journey To The Center of The Earth
The Adventures of Robin Hood
The Wonderful Wizard of Oz
The Land of Oz
Alice’s Adventures In Wonderland
Mutiny On The HMS Bounty
Lady Of The Lake
The Sword & The Stone
The Once & Future King
Dante’s Divine Comedy (and boy oh boy did you need a google/wikipedia to know who all those people he referenced – I spent half my time, even with the footnotes in the book, looking up who they all were to better understand it all).
Alot of Shakespeare.
I starting read some Asminov, Arthur C. Clarke, as well as Tolkien (beyond the Hobbit & Lord of the Rings trilogy), Narnia, all 14 Frank Baum Oz novels,
There are so many I have read, so many I have purchased and not yet read, etc.
