Which book can you read for the whole year?

My next year starts in March. I have to focus on studies more as I have a huge exam at the end of the year. Which classic do you suggest me reading for the whole year (I want a single book)? Like I know some are count of Monte Cristo, War and Peace, David Copperfield, Brothers Karamazov, Anna Karenina, etc. Also if you can, suggest a informative/philosophy book. I have heard about a few like das capital, republic, wealth of nations, principia, origin of species, etc. Anything is fine in any genre until it's sfw. Thank you Ps- my year starts in March and ends at February
