What is the greatest book of all time?

Please respectively state which book is your favorite and why. I'm curious to see what you ladies enjoy reading! My favorite book is Jane Eyre because it's so well written, humorous, and the love story is incredible!
Ps, I'm thinking about starting Anna Karenina by Tolstoy or Rebecca by Daphne du Maurier and would love opinions on them if you've read either! 
Pss, I JUST finished Winter Garden and loved it and am having a book hangover lol that's why I'm needing another book to rebound with 😂
