Here's another. It almost looks like it's part of series, but I don't think so somehow. Looks like they might have created a world in which several stories or books may be released but as separate entities. Amazon only reports it as 720 pages though so it's dropping a bit far from your target.
It's an epic fantasy called
Raven's Heart and although it has a publisher name listed, I can't really find out much about them and expect it's just a front for self-publishing or similar.
Here's an Amazon link:
