This book is good but the Kindle version has a typo every 3 or 4 pages. It's clearly been electronically scanned and not proof read.This really slows down the reading of the book and, for me, removes lots of enjoyment: after pondering over why it says "stem" instead of "stern", or "fee! happy" rather than "feel happy", or why there are random full stops in the middle of the sentences, the pleasure of reading the text is removed.As the Kindle version costs the same as the print copy I would expect a similar about of quality control as a book would receive.
