The Complete 2015 User's Guide to the Amazing Amazon Fire Tablets: Tips, Tricks, & Links to Unlock Cool Features, Save You Hundreds on Content, and Help You Get the Most Out of Your Fire Tablet
I thought this book was very user-friendly, and had lots of helpful hints. I have a Fire and some of the features they say are not available are actually accessible, and some descriptions of functions, such as the charging status, were incorrect. There is a lot of information in this book, in a very readable format. I recommend it!
