One Eyed Reader

The blurbs all over this book make it sound like the series will be continued, but the book itself reads as though it is the conclusion to this quartet, and I believe I've heard that the author themselves mentioned that they had no plans to continue this series, so I'm going to safely assume that this is the last book.
It's a good ending, all the loose ends that I can think of are tied up neatly, and there were a few plot twists that I really wasn't expecting. Throughout the whole book, I thought I knew what was going to happen, but this author surprised me yet again.
Certain aspects of the last few pages seemed a bit rushed, as there were some short winded explanations of what happened after the climax, but I guess it doesn't matter too much; it gets the point across.
All in all I thought this series was pretty good, I probably would have enjoyed the first two books a lot more if I had read them closer together instead of about 14 months apart, but hey, what can you do?
If you're intrigued by the synopsis of these books, I recommend taking a look at them.
