The Sharpest Blade concludes what has been a very intense trilogy. McKenzie has been put through a lot since The Shadow Reader and it's pretty much been non-stop. 
 The Sharpest Blade picks up three weeks after the events in The Shattered Dark. McKenzie has been left in the human world to try to live a normal life. Aren decided that he and McKenzie couldn't be together anymore after the life-bond Kyol formed with her in order to save her life. Now, McKenzie is missing Aren and finding her job at the library to be entirely too boring. When she feels a pull at the life bond telling her Kyol is hurt, McKenzie knows she needs to get to him. 
 Thus McKenzie's life with the Fae continues. When she finally makes it to Kyol she discovers things in the Realm aren't going great for Lena's bid to the throne. There's a false-blood making claims to the throne and he may have more support than Lena. 
 I appreciate the fact that despite the emotional personal trumoil McKenzie is going through she doesn't let is effect what needs to be done to help the Realm. If anything it makes her more determined to live through everything so she can come back and kick both Kyol and Aren's asses. McKenzie has been repeatedly underestimated throughout this series, even though Aren knew / trusted her capabilities more than Kyol (who only wanted to keep her sheltered and protected) he still can't get away from wanting to shield McKenzie from what he feels she can't handle. She does a fine job of looking out for herself and even pulling both of the guys out of tough situations (usually ones they got themselves into). 
 McKenzie's skill has really grown since the first book, but I like the fact that she truly became more than just a Shadow Reader. We know she's the best Shadow Reader the Realm has ever seen. I like that Sandy Williams let McKenzie explore her skills to their fullest extent and it paid off. She did very well strategizing and fighting. 
 So this is the last in this trilogy. Sandy Williams, like most authors, set some things up, however, that could be picked up in the future should she choose to continue stories in this world. I was very happy with the ending. I think that I would have liked a little more though. I almost felt as though we fought and fought and fought and then we got to the end and that was it. I guess I would have liked things fleshed out a little bit more. 
 Regardless, I think Sandy Williams did a great job with eack book, and path to the end seems to follow where it began.
