I first read this long, long ago, in fact between 6th and 7th grade because (1) I had read some really long books and liked them which made me feel grown up, and (2) I read the classic comic version and wanted more.
Be advised when embarking on this that there are a lot of words. I’m pretty sure Dumas was paid by the word so he used plenty of them. But there’s lots of good stuff, too. It was also serialized, so lots of cliffhangers.
There are also a lot of characters, and you don’t necessarily know who they are in the story for some time.
When my son was the same age as when I’d originally read it, we read it together. He always liked having books read out loud but he did a good bit of the reading himself. He liked it. Lots of excitement, intrigue, a swordfight, and tons of conniving machinations, not just those plotted by the Count, but by others–although Count’s actions were probably the catalyst.
We both agreed that Edmond Dantes turned into a real jerk when he became The Count. And he deserved some revenge for sure, but went beyond. There were some very complex characters in there
But boy was there a lot that I had missed in that book, when I was 12! Like the lesbians, the fact that the Count was a drug addict,and much more–but not the fact that he was a jerk and behaved very badly to his former fiancee Mercedes, who had assumed he was dead and had never loved anyone else (although she married).
Now in all the movie versions i’ve seen he gets back together with Mercedes in the end. But in the book, he ends up married to a much younger girl, who came under his protection when she was 11. I thought that was creepy when I was 12 and I found it even creepier when I read it with my son. (So did he.) First that she was so much younger, but mainly that he was a father figure.
