2 books:
The Count of Monte Cristo, by Alexandre Dumas (1095 pages)
"Falsely accused of treason, the young sailor Edmund Dantés is arrested on his wedding day and imprisoned in the island fortress of the Chateau d'If. After staging a dramatic escape, he sets out to discover the fabulous treasure of Monte Cristo and catch up with his enemies. A novel of enormous tension and excitement, [The Count of] Monte Cristo is also a tale of obsession and revenge. Believing himself to be an 'Angel of Providence,' Dantés pursues his vengeance to the bitter end, only then realizing that he himself is a victim of fate."
Outlander, by Diana Gabaldon (850 pages)
"In 1945, Claire Randall, a former combat nurse, is back from the war and reunited with her husband on a second honeymoon - when she innocently touches a boulder in one of the ancient stone circles that dot the British Isles. Suddenly she is a Sassenach - an 'outlander' - in a Scotland torn by war and raiding border clans in the year...1743. Hurled back in time by forces she cannot understand, Claire's destiny is soon inextricably intertwined with Clan McKenzie and the forbidding Castle Leoch. She is catapulted without warning nito the intrigues of lairds and spies that may threaten her life...and shatter her heart."
If you like historical fiction, these two books are beyond comparison, in my opinion. The first one is slow for the first 300 pages or so, but once you get past all the introductions of the relevant characters, oh my goodness! It's a fantastic read and you will not be able to put it down! The original printing was done in French, so you need to find a good translation. I recommend the one I have: Oxford World's Classics, Oxford University Press, edited by David Coward.
The 2nd book is a tour-de-force of fine writing by a very talented author. I read this book in two days...I simply could not put it down! And once I finished reading it, I immediately read it again. It's that good! (Plus, there are 5 other books that are part of the Outlander series, so you get to follow the main characters all over the world! Fun stuff!)
Anyway, I hope you give one or both books a try. The time you put into reading them is well worth it!
