This is the sixth and final installment in Ms. Mead's Vampire Academy Series. I have been anticipating this book for months. I have to say that, while I enjoyed it, I was a little disappointed.The plot was interesting: Rose is in jail, falsely accused of murdering the Queen. The Moroi are anxious for a quick trial, which means they think Rose is guilty. Her friends bust her out of prison and she's on the run with Dimitri - they're supposed to stay at a safe location, but nothing works out like it should when Rose is involved. They end up chasing clues about a possible sibling for Lissa while running from the Guardians, finding an unusual colony of vampires and humans together, and searching for the real killer. Meanwhile, Rose's friends are trying to find the killer and distracting the Court from searching for Rose and Dimitri.The storyline was full of action and stuff was happening left and right. My complaint is that kick-ass Rose seemed almost passive in this book. I felt like she spent most of the story out of it - watching Lissa through their spirit bond. I don't particularly care for Lissa, never have, and for that reason I had a hard time with Last Sacrifice. I also wanted more of Rose/Adrian or Rose/Dimitri. The interaction wasn't there - she only saw Adrian through her Spirit Dreams, and she and Dimitri spent most of their time trying not to notice each other. I was pleased that Rose did make a choice, it wasn't done for her, and her reasons were solid.The ending was good, but quick. It felt like the book was go!go!go! and then wrapped up in the last 10 pages or so. I wish Goodreads would let us do 1/2 stars, because I gave Last Sacrifice 3 1/2 stars.Ms. Mead says on her site that there will be a spin-off series that takes place in the VA world; I'm looking forward to it.
