Great addition to the series, and it's definitely best to read after you have read the previous installments.
Hard to review without spoilers, but there is a nice plot twist somewhere along the way, all the usual snark and slightly twisted humor that you love from the characters, a really really adowwable little girl who steals the show everyone and then...
In essence I had a great time, devoured the book in one sitting and can't wait for next installment!
