My Name is Red by Orhan Pamuk is very much a new book to me. In fact I hadn't read any Pamuk before this book, which I'm still reading. From the given evidence I like him, though. The book is dense and perhaps somewhat challenging, due to the multiple narrators. But it gives a fascinating view of the Medieval Ottoman Empire: placid and conservative on the surface, but containing a great degree of debate and rebellion under it.
The thing of calling Europeans "Franks" was also used by Kim Stanley Robinson in The Years of Rice and Salt, where it referred to a nearly-extinct species. Apparently it's a real thing. Kind of odd, since the actual Franks were just one of many Germanic tribes. But language is always a funny thing.
