well, i guess i feel accomplished? this was an easy read in the sense that i was able to finish it in nearly one sitting, but the book itself was a little disjointed. there was just so much faffing about going on. honestly, everything necessary could have been condensed down to 10 pages. not a very solid ending to a series, in my opinion, but im glad i saw it through.

I had a love, hate relationship with this series from the start. I love the plot and premise but I find Rosie to be annoying. She is a bit unlikeable and also whiny. However, the plot and premise of the trilogy really helps the reader to continue on past her. This is the final book of the trilogy based on dream mining and adds a couple really intriguing characters that end up playing a good size role in get the finale underway. However, I found the ending surgery to be very unbelievable. Are we ...more

The Keep of Ages is the third, and final, installment of The Vault of Dreamers series by Caragh M. OBrien and if you havent read any books in this series, you may want to check out my earlier reviews and then of course, go dive into book one so you can see why I enjoyed this series so much. With that said, I will try to avoid spoilers for this third book but cant promise for books one and two so now you are warned.

*My Thoughts*

The Keep of Ages is the third and final installment in author Carah M. O'Brien's The Vault of Dreamers trilogy. As the story picks up, Rosie Sinclair returns home for the first time in 6 months to find her family missing. Rosie knows that her fight against Dean Berg won't truly end until she can find a way to stop him once and for all. Even if that means traveling to the ends of the world. Rosie wanted to expose

I liked  The Vault of Dreamers loved  The Rule of Mirrors , and quite enjoyed  The Keep of Ages . In all, it was a strong series that I'm glad to have read. I still feel like the second book was the strongest in the series, but I liked the way this one wrapped up the series.

The tone for this book was quite dark, both atmospherically and psychologically, and it worked out very

Wow. I have to say, plot-wise, this trilogy was amazing. I've never read anything quite like it and had a lot of fun reading it. But, it could've been a whole lot better with a more mature MC and no romance. Then I might have considered rating it a lot higher.

The book caused me more stress than I was expecting. I'm not sure I've ever been that stressed... or scared.

I LOVE Rosie so much! She's one of my favorite characters ever. I feel like every time I had a thought about something she would say it.

There's still unanswered questions so I wish the series wouldn't have ended. I hope she writes something more in this universe even if it isn't exactly about Rosie.

Well, I've got to go start reading the series again!

The Keep of Ages is the third book in this series, and it was just as engrossing as the first two. Rosie is determined to bring down Sandy Berg, but she's thwarted by him at every turn. As we learned in the second book, he is able to spy on her seemingly everywhere. Now her parents and sister are missing, presumed by Rosie to have been taken by Berg, but where? How will Rosie find her parents and Dubbs, and stop Berg, short of murder?
This book is a satisfying conclusion to the Vault of Dreamers
Jessica (a GREAT read)
Caragh M. OBrien brings an exciting conclusion to The Vault of Dreamers trilogy with The Keep of Ages! Things in this one were pretty intense with danger looming around every corner! It was a pretty fast paced read that I was eager to see through to its end!

Rosie is off to find her family before Berg can get to them, but shes quick to learn that Ian is also on her trail. Though she soon learns that Berg is, once again, one step ahead of her. Her family has been taken and being hidden somewhere

How I Came to Read This Book: I reallllly liked The Vault of Dreamers but the series definitely went downhill from there...

The Plot: So at this point, Rosie had the chance to kill Berg but she didn't. So naturally, Berg stole her family away, right as Rosie (finally) went back to see them in Doli. She gets a random lead from her little sister Dubbs as to their whereabouts, which leads her to Lavinia, the former head of The Forge School, who fills her in that her family might just be kept at

I gave all three of these books a score of three stars. I'm waffling about that, because there was so much wrong with them that I could have rated them lower...but I'll stick with it because of the inventiveness. No matter what problems this author may have, she has an amazing imagination, that's for sure.

One other thing for which this arc of three books gets a dubious award: The protagonist, Rosie, is without a doubt the stupidest, most gullible girl on earth. Sweet, well-intentioned, a real

Oh my goodness, I can't believe this series is finished! I feel like I have been waiting for book three for so long. I am so happy to know how the story ends, but I am so sad that I won't get to spend any more time with these beloved characters. If you weren't already aware, I am a huge fan of Caragh M. O'Brien.

This book was an interesting adventure. This scifi world is a unique one. Not only is it futuristic with crazy futuristic medical developments, but the settings she crafts within the futuristic world are out of the ordinary in their own right. The town of boxcars, the theme park, and the underground vault are all intriguing settings. The plot was exciting. I missed Thea's perspective, but from the way everything played out, I can see how it wasn't needed. Although when we ended the other book, ...more

This book brings the Vault of Dreamers trilogy to its conclusion. Rosie takes center stage once again while Thea, the girl who shares her consciousness, plays a secondary role. Rosie is determined to stop Dean Berg from mining memories and implanting them in others. She is also driven to save her family from Bergs clutches. He uses Rosies parents and younger sister as weapons to make Rosie follow his orders. Berg is obsessed with her, convinced she is the key to his research. Rosie has separated ...more

I was given this book by the publisher for an honest review.

Let me say first, I do not generally like 1st person stories. The seem clunky to me and often I can't finish them. This book is in 1st Person but not nearly as annoying as many I have read.

The heroine is Rosie Sinclair and she is in the process of escaping from the evil Dean Berg. Her previous encounters with Berg have nearly ended in her death and she is not anxious to have him capture her again. You see, Rosie has a mind that is full

Fans of this dystopian series will enjoy the twists and turns of this satisfying end to the trilogy.

Rosie has finally made it back home but her sister, mother and step-father are not there as Dean Berg has once again gained the upper hand and kidnapped them.

Rosie is still committed to exposing to the world how Berg is using the vault of dreamers as she she knows he will never stop his pursuit of her so he can once again access her vivid dreams as a way to fight his demise due to Huntingtons

This entire series was well written with just the right amount of suspense. Caragh OBrien also sent many subtle red herrings throughout each novel, which was impressive. There were a very few 4 letter words, mostly shi*, and the romance was basically clean as well. This was refreshing in light of current mainstream YA literature.
The main character is a bit stupid when you consider all of the times she allows herself to get in helpless situations, but without that, I guess there would be no

The third book was more in line with the second book. The writing, I think, was better than the other two. Stopping the split point-of-view helps this book. And the first few chapter filled out Rosie's relationships, which has been very much needed. Although, my dislike for Rosie continued with her very questionable actions. She is just a teenager and I do not understand how she was able to do some of the things she did, because I definitely would not have been able to.

I love this series, I've read the books since they came out. I've waited for every book eagerly, and I have been very happy with it. When I got this book I was so excited to read it, and when I did I loved it, but the end seemed a little rushed.
Linus and Rosie's relationship wasn't something that was part of this book much which made me sad. I loved their relationship and I would have liked to have known what went on between the two after this ended. I want to know what happened with Dubbs, and

I have waited with anticipation for this final book in the trilogy, but I was disappointed on several pieces. I felt like I was transported to the apt in Cali and to Grisly lark. Those details were great. I loved Dubbs and felt her character was well developed along with Mrs. McClellan.
I kept thinking the story would've been more believable if Rosie hadn't charged right into the vault to get captured. That just seemed dumb! I liked the build up and planning of the second venture into Grisly. It

Finally found a way to finish this book (I'd started it in a Barnes & Noble and then couldn't find it anywhere!)
Unfortunately, this last installment didn't do it for me. The premise behind this series intrigues me, and like I've seen from other reviewers on here, O'Brien gets points for creativity, but I found myself more determined to finish so I could finish rather than because I wanted to know the ending. Maybe it's because I took so long to read it, but the plot felt ambling and
