Please tell me this is a mistake

The Kindle title Practical Variable Speed Drives and Power Electronics (Practical Professional Books) by Malcom Barnes is ludicrously expensive, according to Amazon.com's website. The price? $41,916.00--reduced from $52,395. Now let's see, that's about 117 Kindle 2s, or as the lone reviewer says, more than a really nice car. Granted, it's a title with a narrow focus for mechanical engineers, but my goodness, are they serious? Thanks to Bibliofuture of LISNews for the link.
