Obstetrix by Naomi Kritzer

Obstetrix is a fast paced thriller and can easily be finished in a day. 

Doctor Liz has been kidnapped and taken to live amongst a fundamental cult. She will be required to use her knowledge as an OB/GYN to care for the women in the cult. If she refuses they won't hesitate to take her life. Dr. Liz is also the only doctor in the compound and will be expected to take on other doctor duties.

The compound is isolated and Liz has no idea where she is being held captive. She and the members of the cult are under constant surveillance and have little to no contact with the outside world. Dr Liz needs to find a way out - to escape and save the girls who are trapped.   

This book is a look at some of what we know that exists within fundamental world and can be taken as a cautionary tale.
