You can get FREE free on the Kindle (and Kindle iPhone app if you don’t have a Kindle) now. It’s been up for a few days and the free offer will end on Wed, Jul 22nd, so get it now. [UPDATE: the free offer is now over, and the book is now at the usual discount price of $9.99. It’s still available for free on Scribd, Google Books and Shortcovers, as well as in audiobook form on iTunes] As you can see from the above screenshot, it’s already the #1 Kindle book. (US only, I’m afraid.)
It’s also available for free on the Sony Reader, also for one week.
The book is also available for free (for one month) on Shortcovers, where you can link to individual chapters and pages.
For those of you outside the US, local free versions will be determined by the publisher in each region. Please stay tuned.
