I don't know how long this will last, but The Last Boy, Jane Leavy's recent bio of Mickey Mantle, is currently free. It's a new edition enhanced with audio/video supplements that are only accessible if you have an iPad, iPhone, or iPod Touch. I downloaded it to my K3 and of course I didn't get the audio/video stuff but otherwise it seems to be the complete book. The "regular" Kindle edition is still listed at $12.99, where it's been stuck for months. I can't find it with Link-Maker but I'm providing the link below. Be sure to check that the price hasn't changed before you 1-click. Thanks to William Smith on the Amazon Discounted/Price Dropped forum.
