I loved this world, and the characters. I've never really been a fan of Wonderland stories (the animated movie scared me as a kid), but this one was new and fresh and a wild ride. Meyer's writing is delightful and whimsical and fitting for a story about Wonderland. I have two small complaints: 
 1) the story took too long to get going. I wasn't really interested until about page 60. But after that, I couldn't put it down. 
 2) Catherine. Her character needed to grow a backbone. 
 Don't read this spoiler unless you've read the book! 
 (view spoiler)[ Now about the ending: I died. I kept hoping that the story would change somehow. Or at least that Jest would give his life to save Cath, or something noble and romantic like that. But no. Or AT LEAST that Cath would sacrifice her heart for Jest's original goal, which was to stop the war in Chess. But the ending had nothing good. It wasn't bittersweet. It was plain old bitter. Especially since MOST of the bad things could have been prevented if Cath had stood up to the king and her parents earlier. Just don't agree to court the king in the first place, then run off with Jest and live happily ever after. The end. (hide spoiler)] 
 I really enjoyed seeing Meyer's newest story, and I'm excited to see what she writes next.
