Fantastic. Awesome. Clever. This is surely a book we will read over and over again, which means I'm going to have to actually buy it for Hen's home library. Oh, darn. (Not really.)
The only thing I want to note about this book is that it is infinitely better if, when reading aloud, you can create voices for each of the characters. There is much banter between Professor Steg and the father as they fly around in the "Floaty-Ball-Person-Carriers". There are wumpires with accents, Splod the god of people with short, funny names, and green globby peoples. Also, ponies. (And you thought it couldn't get any better.)
There is a Usual Suspects kind of ending that I appreciated.
Did I mention the illustrations along the way, because those are fantastic. If you have a kid that likes books, this is one for the bookshelf.
18 down plus 34 to go.
