As the two first books focus more on Alex and Conner, I am glad that the third one develops even more, making all the fairytale people and creatures felt more realistic and alive, like you can really connect to them. In the third book, changes happen everywhere as everyone continues to live their life after the portal between two worlds is closed. There's a lot of going on within a blink; details and twists everywhere, all tied up in one big red line led to one big twist in the cliffhanger end (yes, cliffhanger). I am glad that Colfer presents more character developments and additional backstories in this book, though some still are underused. And new adventure in new places, such as Germany and London; I pretty much drown into it, Percy Jackson-like. And praise Colfer for finally bringing a real romance in the installment; the twins are now having crushes! And I have to say that Bree is a nice addition to it, though her character is kinda swept off in the half-end.
Finally said, Land of Stories : A Grimm Warning is an incredible imagination with excessive amount of twists presented in one thick bundle of classic turn. I seriously recommend you to read the entire series because I had so much fun throughout. And of course, I will be patiently waiting for the fourth book to come out next year.
