I haven't read The Bronze Horseman, that sounds really cool (I think I need to add that to my goodreads) I have two books that come to mind, you may already have read them:
Sarah's Key by Tatiana de Rosnay
Guernsey Literary and Potato Peel Pie Society by Mary Ann Shaffer
I liked the GLPPS book better, although SK was very good. They are both historical fiction WWII novels and I enjoyed them! They are not as big and thick as you were talking about, more like 300-400 I think...I read them both on my kindle, so it's hard to say, lol.
If you read them, you'll have to let me know if you read them and what you think! HTH
