Matthew Heines has just published a wonderful book Killing Time In Saudi Arabia. It details his 18 months in the country working as a contractor teaching English to the Saudi Arabia National Guard.
The book is one that I greatly enjoyed, there is a surface layer of humor but when you dig there is a much more serious layer. It is all about trying to reconcile western customs with those of the guest country. There is little room for error, and errors can be costly.
In Matthew's case not only was he faced with the culture shock of the country, but the culture shock created by his employer.
