Hoban tosses off a droll adventure that derives its fun from a few modestly absurd conceits. "ACE DRAGON LTD." is written on a round iron plate, like a manhole cover, that John finds on the sidewalk. Soon he's talking through the plate to a dragon who explains that LTD. means limited because "I can't do everything. I can only do some things." One of the things the dragon can do is spin gold into straw--an unpromising talent that proves useful when he runs out of petrol giving John a ride through the sky. They land on a gold moon, would jump to earth if they had something soft to cushion their fall, and there it is--straw. A pleasing trifle, with Hoban's offhand, offbeat aplomb handily comple-mented by BlaKe's casually energetic sketches.
