Is there a sample chapter? It's hard to know if I want to purchase it without knowing anything about how the book is written or whether it tried to achieve its purpose.
On the 'Get the book' link, the last paragraph states:
'We have set a minimum contribution of _FREE and a suggested contribution of $19 to cover the time and investment the four of us put into this book.'
The 19$ is the _suggested_ price, the actual sum is up to you. As you guessed it is a collection of interviews.
