For those of you waiting for it to be on Google Play, here is one idea that might work: we are in Beta on a Morgan Rice app (free) which is in the Android App marketplace. Here's the link. You can download the app for free, and I hear there might be a way to download the book via the app. Not 100% certain.
The other option is to visit www.morganricebooks.com and buy it from the site in a PDF or EPUB format--you can read it right away, but I don't think the file will import to Play.
In the meantime, I keep asking Play every day! They are in the midst of a transition and they promise this is a one-time bug. We'll see! Of course, feel free to contact them yourselves, too.
