This website offered an ebook about prostitution in Costa Rica. Kind of a strange way of retrieving information about Central American sex workers, but maybe the author does not want his info to be distributed for free. I have never looked into the ebook, but it might be worth the small fee compared to the amounts of money newbie gringos tend to throw around with on their maiden trip to CR.

The website has been disconnected. The link leads to an archived version for reference, only.
