This book can provide plenty of help and guide for anyone traveling to Pakistan, foreigners in particular (she mentioned a few things in Lahore, my hometown, which even I did not know). I picked the book from my father's bookshelf to kill my time and ended up reading all of it. She explains most things about the local culture extremely well, without the usual negative tone that most other authors unconsciously get into (no offence for anyone please).
For me if a book gives you the information that you need and makes you read more than what you initially planned, is a five star, so is this one!
