Great book for Japanese script

A couple of days ago I purchased a book about reading and writing Japanese (Amazon link in the title). Although I would say that it is fairly poor for written exercises the reading aspect is handled very well. In a few hours of effort I have learnt over sixty kanji and by the end of the book I should have learnt double that. I am impressed with how easy the author makes it! If this book is anything to go by then I will be trying out others in this range.
