Twelve years ago, when she was 26 years old, a Kuala Lumpur woman named Azlina Jailani came to a momentous decision. She converted to Christianity and changed her name to Lina Joy. Joy, now 42, today is at the epicenter of one of the most difficult issues in Malaysian society, one that authorities are approaching with something akin to alarm. What she would like do is marry her non-Muslim boyfriend, a cook, and get on with her life. That appears to be impossible because, under Malaysian law, Joy is still a Muslim, regardless of her beliefs.
