The Forsaken Throne
The Kingfountain Series - Book #6
by Jeff Wheeler
OK, so this one gets a little crazy with a journey into an alternate world. I didn't realize until afterward that the alternate world is a crossover into Wheeler's other series, The Muirwood Chronicles, which I haven't read yet.
That said, this book was a pretty good conclusion to the series. My only complaint is that things fall together a little too neatly. But otherwise, I was hooked from about the fourth chapter until the final pages. I think I read it in 2 days.
