I've never written a customer review on here, but the one Canadian review of 2 stars is a travesty. All a 2-star review says is "I failed at knowing my own tastes."
SO: If you like work that is brave and revelatory, you want to buy this book. If you like literature that breaks new ground for others, like good research does, you want to read this book. If you like books full of heart and wisdom, you want to read this book. Whether you are religious or humanist, you want to read this book.
