Excellent book, have the paperback edition, but... $59.99???!!!!! That HAS to be a mistake. The Portuguese version is $5.99! PLEASE tell me someone put the decimal point in the wrong place.

It is a great book, but $13 on Kindle. Need to revisit pricing...

I love this book. I have read this book multiple times. I would like to have this book in digital format too but will not spend $59. is this a mistake?
