The official release date was July 27, so you can imagine my surprise when I saw this on Amazon.com
"Want it by July 20? Order it in the next 21 hours, 25 minutes and choose One Day Shipping at checkout."
This means if you order before 1 PM on July 19, New York time (17:00 GMT), you'll get the book on July 20th
I hope you enjoy it!
