** spoiler alert ** 
 Okay, so here's what I think: It took longer for me to actually get the book so I read other people's reviews in the waiting and was so excited to see that most of them were great, saying that it was an excellent ending -even if it didn't go that way for some characters. When I finally got it I was expecting a lot of Rose/Dimitri moments, great dialogs and funny replies.. as usual, even more once I read other reviews saying the book was a lot like the first books were... 
 I was so disappointed when I finished it. I mean, it's okay for books like Blood Promise, or Spirit Bound to be a bit slow or boring since they had to introduce a lot of 'story' for the ending to be as planned, but Last Sacrifice? I found myself skipping a LOT of the paragraphs, and that never happened to me with Richelle's novels (only with BP, but just the beginning). 
 But what bugged me the most was the romance... I read lots of people talking about the constant 'tension' between R&D, but where was it? The only scene I liked was the first one, when Rose punched him. Now THAT'S some classic VA scene, but the rest I found so boring. I liked that Dimitri was sensitive, I think it was sweet how Rose helped him, but really, I found their moments so uncreative. There was too much thinking going on... Rose telling us how she feels...but it was TOO much, especially for a 6th book! We know how she feels! I wanted more dialogue, more action... and when he finally says something, guess what? Its repeated dialog. "You're so beautiful, it hurts" Come on, give us something new! And if that wasn't enough, then Rose goes on with her mind rambling(again)and tells us how he had already said that... in THE CABIN! the cabin? NOT TRUE, he said it when he had the lust spell... Come on Rose if you truly loved him you gotta remember those details! Then there's another scene where Rose says 'you see something you like" AGAIN. All I needed was a little more creativity, I love Richelle and her novels, and VA is still my fav series, and will continue to read them, but I feel she wasn't at her best here, didn't put much effort creating new dialog or even checking her previous books. 
 I really do hate when she doesn't describe things. I mean, I know its a YA novel, but the lust spell scene was way hotter than the one in this book, and it was the first novel! I don't want an explicit description, don't get me wrong haha, but I wouldn't mind some extra info besides "what we did then, was more than lust" and then off again to save the world. I think that a novel can still be deep without insight of her every thought overly explained. It was too much. 
 To be honest, I was rooting for Dimitri, never did I want Adrian to be the one she ended with, but at the end I did. Adrian seemed like the only normal character out there, he sure seemed more passionate about Rose than Dimitri. VA novels were classic for their awesome characters. Here I found them annoying. I really couldn't stand Rose. Like her complete overreaction after killing Victor, come ON. He tried to kill you and your best friend before.. She didn't seem to mind when Eddie killed a moroi for the same reason, but when she did it. THE SHAME! It was like they needed a moment with Rose vulnerable so that Dimitri could return the favor but it didn't work for me. 
 Its a pity cause I REALLY like Richelle's novels, and I think she's an amazing writer. I just had a big problem with this one especially considering its the only ending I'm getting. However, I'll read it again, maybe it grows on me or something. I surely hope so! Sorry for the loooooong review. I might just relate to Rose after all. No really, I HONESTLY wished I could give 5 stars to this book, I hate it but I didn't like it! 
 Ps. Oh! I forgot, I would never thought back when I was reading VA, that the last booked involved them living with cave people. Haha was it really necessary?
