The book is a top seller at 'Mr. Books' (in Islamabad), the only place in Pakistan where it is available, the report added.

The bookstore had ordered a couple of hundred copies of the book from India, and despite its high price tag of Pakistani Rs.1995 (about $24) - all are sold out, it said.

The owner of the bookstore was apologetic about the price but said he had incurred heavy costs transporting the books from India to Pakistan via Dubai.

There are only two weekly flights from Delhi to Lahore, and the quickest way to ship in the books was through a third country, the report said citing the owner. Another bookstore in Islamabad, Saeed Book Bank, said it was expecting a consignment of 500 copies soon.
