This is, quite simply, one of the greatest books I've ever read. It was worth every one of the 99 pennies. Featuring clear, easy-to-read prose and a dazzling display of logic, I am sure it is one I will be picking up again and again.
As a bonus, there is a great picture of the author at the end.
You won't go wrong in grabbing a copy of this soon-to-be bestseller.
