Dude, why title your book Power-of-10 if you're just gonna let the designers of the cover throw the hyphens out:
And then quote a critic who has the title rendered correctly?
Okay, one chapter in and I'm realizing that consistency is not terribly important to the editors. Remind me never to submit anything to this publisher. I'm all for not having the "art title" match the actual title perfectly (especially with colons and ampersands), but not when people are liable to pick up and perpetuate the wrong spelling.
