YAY! I can't say how happy I am that I finally get to read this book!! :D :D I bought this right after I finished my AP exam, so it was extra special, haha. Anyways, onto a review... 
 Spoilers for those who haven't read the previous books! Perhaps some spoilers for this book? Not anything major though. 
 Bitterblue's now 18, and she's running the kingdom of Monsea. Her father, Leck, is dead, but he still seems to live on. Although she's advised to look forward and forget the past/Leck's reign, Bitterblue doesn't feel like she can rule being so oblivious. Her advisers freeze up when she asks questions, so Bitterblue sneaks out of the castle to find answers. She goes disguised as a commoner and hears the stories her people tell (view spoiler)[ Like Kasta and Po :D (hide spoiler)]. Along the way, she meets two thieves, Saf and Teddy. Saf is a Graceling with purple eyes...yet he doesn't even know what his Grace is. His best friend, Teddy, is really sweet and understanding. They own a printing shop along with their sisters, and for some strange reason steal gargoyles (you'll find out why in the book). Also, since Bitterblue won't say her name, they call her "Sparks". Soon Bitterblue registers how many lies (some betrayal!) she's living with, and she makes it her job to clear everything up. 
 Man, I want a Grace so dang badly!!!! I would want one like Hava.... :) 
 Bitterblue is also very smart--she caught some things that I wouldn't have even noticed! The book is full of great humour and dialogue! Man, a pro of having a Kindle is being able to bookmark the funny scenes :) The con of it is that I didn't know so many pictures were in the book! I might just wander into a bookstore to sneak a peak of the illustrations; the e-book pictures just feel incomplete. I really did love this book, but I didn't feel like it ended well enough :/ Perhaps another book, Cashore? :D :D Yes, please!!!! (view spoiler)[ I would like to know what happens to Saf (hide spoiler)] I love how the keys have such meaning throughout the book--so much discovering! 
 If you've read GRACELING and FIRE (and if you haven't: what are you doing? READ IT!), then you'll definitely recognize some people.
