Just finished reading this book...
Most of it is set in a fictionalised Muslim country, and particularly a fictionalised major market town there. All the characters and events are allegedly real, but they weren't necessarily in the same place to start with.
As a way of telling true stories about Muslim Background Believers in Muslim countries, though, it's quite sensible. And as would be expected, some of the stories are quite moving.
All in all, it's really encouraging to read about how God is working in countries like that, to read about the perseverance of the church, and it's a real spur to prayer.
There's quite a bit on how to respond as well. Definitely worth a read..
Edited to add: Of course, this sort of thing also happens in England.
