From what I've seen so far, it's a good example of a thorough treatment of an important subject which the author has been careful not to belabor: it's a good topic for a short book, not a massive one. Knowing when to stop is a good gift to have in a writer, and I'm looking forward to reading this one to seeing how well Mr. Phelpstead covers such an interesting topic. I strongly suspect it'll be a serious contender for next year's Mythopoeic Award.
The only thing I'd warn against is the price-point. Not for the trade paperback, which is out already, and v. reasonably priced (you can get it online for around $20). But the hardcover, which I got on the assumption that it probably wdn't have a US edition and any paperback wd be years down the road (quite wrong, as it turns out), comes in at a staggering $148 (sans tax). Here the outrageous pricing for books from university presses and equally outrageous prices for imported books seem to have run together into an ungodly result.
So, profit from (not following) my example. Time now to return to and finish up the Horne biography so I can move on to greener pastures . . .
