My son was very upset when the book didn't have pages. I called and received a new book, which also wasn't the correct book. Needless to say it will go in the garbage. What a rip off! They should take out all reviews that are not written by "Amazon Verified Purchase". This has never happened before.

My wife purchased my husband the first Kindle Fire for Christmas in 2012. This tablet was never fully charged or used much and failed to start on day three. In March 2013, as we were watching TV with our children, there was a loud bang sound. He turned it off, waited about 45 seconds, then put it back on. That seemed odd. When you hit play on your tablet, no matter what app, that page is displayed. But if I press any other icon - like home button, calendar, search function, etc....
