Both Barnes and Noble and Amazon have In the Land of Invisible Women on sale for $2 for the eBook version today.
I picked it up last time it was on sale, and it’s a good read. Nonfiction, it’s a memoir of several years the author spent as a female doctor in Saudi Arabia. She’s Muslim, but was raised in the west, and it’s a good insight to what it’s like for a modern woman to live/work in a Muslim country. Definitely worth $2.
