I checked this book out from my public library a few times as a kid, but never owned a copy. Cut to twenty years later, I had long since forgotten the author and the title, but remember really loving this book, as well as the author's other books in this series. I had a hell of a time tracking it down, but finally, after some rigorous eBay searches I finally found it and bought a copy immediately.
Revisiting a story from your childhood, especially one I've mythologized as much as I have this one after losing it for so long, can be dangerous; how often does something that was great as a kid really hold up as an adult (I'm looking at you, He-Man cartoons). Well I was pleasantly surprised that Dr. Dredd's Wagon of Wonders DOES hold-up, at least as a solid children's novel. I had minor issues with plotting, mainly how the premise is that Dr. Dredd has the ability to promise and deliver to a town anything they want (at a steep price, of course) but then the story revolves around Calvin, a boy he owns like a slave who actually has the power. It makes Dr. Dredd seem a little weak that he's so dependent on others to pull off his magical feats.
Nevertheless, this is a really well-written children's book that doesn't talk down to its audience, and features pro-active characters and a great ominous tone. I'm so glad I managed to reconnect with this book and this author. Now to track down the other books in this series...
