After I finished reading this with my son before bed last night, he declared it was the best book he's ever read. He's a bit of a bookworm (like his mother) so this was a fairly weighty statement. I too was impressed with this sci-fi children's fantasy. It begins with the mother going away to a work conference and leaving the father to take care of the children alone for a few days. They run out of milk and the father runs out to buy some more. However, he takes longer than the children expect, and upon his return tells them of his wild adventures on his way back. I laughed out loud in several places. The drawings were a great addition.
One of my favorite exchanges:
"I think that there should have been some nice wumpires," said my sister, wistfully. "Nice, handsome, misunderstood wumpires."
"There were not," said my father.
