Guantanamo Bay is the most secretive prison camp and houses some of the world's notorious terrorism suspects. The main characters in the trilogy, Anastasia Steele and Christian Grey, are a big hit in the lock-up. The books are the most-checked-out of the Guantanamo library.
"They've read the entire series in English, but we were willing to translate it," Rep. Jim Moran said. "I guess there's not much going on, these guys are going nowhere, so what the hell."
The books have sold more than 70 million copies worldwide, and the movie is set to premiere in August 2014. Any books for borrowing at Gitmo are censored for sexual content before being made available to check out.
