Frankly I just loved it. Is it the best written book in the world? No, but it had real charm and great characters and true aliens. I loved Wave, and the whole new world that Kimberling has created. I enjoyed spending time with Gaia and her Happy Snak world, oblivious and yet now central to the entire alien human detente, and I love how she indirectly influences the entire world of the Kishocha. Great way to spend a few hours, and I made the mistake of down loading it at 11.30 and then blinking at 2 am and thinking, I have to finish this in the morning! It's a proper length novel, not a novella that you just gulp down. I rate it a keeper and a reread.
The ending, while complete, was also open ended enough that we could visit this world again, and I sincerely hope we do!
