I realize I don't have a review of the first book in the series: The Search for WondLa as I read the ARC before my Goodreads days... :) 
 I didn't realize how much I really loved the first book until I got midway through the second. I mean, I must have really liked it if I picked up the second, right? I think I picked up the second more for the fact that a book of this much imagination and uniqueness (I'm referring to the first, of course) does not always get the attention it deserves. Had anyone else heard anything of the first book when it came out? I hadn't. I don't know anyone who has read it. And I was having some trouble coming up with reasons on why to recommend it. After all, it's classified as middle-grade fiction in the bookstore - an area that hasn't really gotten AS MUCH of the crossover effect of the YA/Teen books. I only mention this because I think it's a pretty hefty book for a middle-grade reader, with an advanced vocabulary (for that age, or so I think anyway), and it has a complexity to the story that is not as typical for the age group. I think it could have more success with those of us adults (woof) that like crossover. 
 DiTerlizzi creates a magical, futuristic world where aliens and humans all cohabit (but don't mix?). The world seems so grand and yet so small at the same time. Almost as though humans and aliens catapulted to this strange existence leaving much of their present situation unspoken - amongst themselves mostly but also each other. (Though of course this thought could be a result of the series doing what series do, leaving unanswered questions for future books. And I don't mean that that's too distracting in this case. Just an interesting aspect of the story that can be reflected on our present society and topics that we tend to ignore because of that inherent desire to get away from it all.) I think about one of the alien societies in this second book that thought they could maintain a peaceful existence by remaining isolated from the rest of the world. (On a more literal note, they live in homes that are elevated off the ground.) Sounds ideal, right? But how can a society grow if no one leaves the nest? Rovender Kitt, companion to our protagonist, brings this idea home in this second installment. Our conception of home and societal obligations and the importance of communication and all these other grand "things" are topics to ponder over a very entertaining children's novel. 
 I am being extremely boring in this review. I get it. What I do want to get across is that this is a fun and interesting book (unlike my review!) and that it should be read slowly, absorbed, and reflected upon. There is much more to this story that adults (and you intelligent childrens) can pick up on and appreciate and I really felt the growth in the second novel that allowed me to appreciate the work (as a whole) more. 
 I might add more later. I really like this one.
