I've really been enjoying this series, tearing through a new book each day or two since I discovered them. I just can't get enough. Regent, book four of the series, was no exception, and I found the story engrossing and engaging, and I couldn't wait to find out more: the secrets of Dragonhold (Runes? Secret rooms? Hidden artifacts?), the mysteries of dragon riding, the fate of the south lands, the intentions of Thorakis, the driving force behind the black dragons, the demons, or the assassins (Are they working together? Are they a new threat spurned by Istra's power, or an old enemy with new powers?) Unfortunately, the author opens all of these doors, as well as introducing many new characters and relationships, without adequately developing them or yielding any substantial information. There are some minor details, regarding certain characters, that I wish the author had taken more time to explain. At this point, I'm not sure if the author will go back to touch on them in the next installment, or if I'm just supposed to go off the information I've been given.
I didn't feel like any other book in the series was ended in such a jarring manner, they had complete stories that were satisfying, but each story left you wanting to know more about the world and the Herald's journey. Although Regent was equally interesting and well written, it really feels like they just chopped the ending off the book (or maybe a whole half of it!)and it really detracts from the book's enjoyability. Instead of leaving me thirsty for more, I am kind of frustrated.
I will definitely continue reading when book five comes out, but probably won't get six if five is ended in the same manner. Personally, I would suggest putting off on Regent, and waiting until five comes out, with the hopes that you will get a *complete* reading experience by getting both books together.
