Do you mean
Ivanhoe by Sir Walter Scott?
Published in the 1800's and it really
isn't difficult to read dude.
I would've
easily been younger than you are when I got my copy of it.

It shouldn't be too difficult to find this in a second hand bookshop somewhere
Another book you may possibly want to check out is
The White Company by Sir Arthur Conan Doyle.
I read that around the same time I read Ivanhoe.

Still got both books, older hardcover editions.
