Alif the Unseen by G. Willow Wilson

From the post:

In another wryly self-aware passage, a (white American) convert to Islam questions why eastern writers are able to write great western literature, while the reverse doesn’t hold. Unless Lawrence Durrell’s Alexandria Quartet might qualify as eastern literature?

There’s a very simple test, replies Vikram the Vampire.““Is [the book] about bored, tired people having sex?”

“Yes,” said the convert, surprised.

“Then it’s western.””
