Oh my God. I completely loved this book! It was all about Damon and Elena, and that's what I loved about it. It shows a softer, more vulnerable side to Damon he only shows around her, and she begins to realize that maybe Stefan isn't her only world. The Dark Dimension story plot with the kitsune keys was fascinating.What I do have to complain about is everything that's happening in Fell's Church. The book is mainly about Damon and Elena getting Stefan back from Shi no Shi, right? So why add the random story plot about what's happening back in their small town? And the thing with Caroline turning into a werewolf and having puppies or whatever was really unneeded. Not too many people care about that character enough to see her in the book.And I also hate the ending of the book. I felt it was a little rushed. It's like I barely knew what was going on. I didn't feel it was necessary to have that in the book, she could have waited until the last book to put that story plot in and explained it a little better, because it seemed to move way too fast and with little notice.But otherwise, completely great novel.
