I was not surprised to see so many middling or outright negative reviews of this book. After finishing it, I was torn between giving it one star, or five. Five stars because readers finally, finally get some concrete answers. We got to see exactly what happened the night Connor lost his abilities; many of the "mysterious" actions of characters like Briallen and Nigel are explained; the faith stone and dark mass are resolved; and Maeve takes center stage. The last third of the book (minus the ending) were exciting and action packed. There are some startling, and really cool, revelations about Connor, Bergen Vize and Convergence. All these factors should have added up to a five star book.
However, I had some serious issues with the book. First, nearly half of the book was recap. I found myself at page 104 and nothing had happened beyond finding a couple dead bodies. Connor spends a lot of time roaming around the Tangle, telling the reader what had come before. He doesn't DO anything but move from one location to another. Every pivotal event was recalled, and the state of his personal relationships with anyone of consequence. It felt like the author didn't trust the audience to have read the prior five books. When the storyline does kick in, it goes at breakneck speed, resolving pretty much every plotline, right up to a cliffhanger "King Arthur" conclusion that leaves the entire world and nearly all the characters in doubt. Someone compared this to the Sopranos ending. Nope. It was far worse. Sure, we didn't know if Tony lived or died, but you knew what happened to everyone else. Not so here.
I hadn't read anything about this being the last Connor Grey novel, as mentioned by other reviewers. If there is more to come, I would not hesitate to give this book 4 stars and preorder the next one as soon as it appears. I do not mind a cliffhanger, and this one is a doozy, if what comes next is still on the horizon. If this is, indeed, the last - I'd give this book one star and not recommend the entire series to anyone. This "conclusion" wasn't just disappointing, it felt like a betrayal (the kind that keeps you from reading more by an author). Since I'm unsure, I went down the middle and gave it three stars. Recommended, but with grave reservations.
