The original Zal story by Ferdowsi gives a very moving account of an infant who had all odds against him - he was left to die in the wilderness and a giant, benevolent bird rescued him and became his guardian angel. This tale thrilled me; I've always wanted to write about it.

I write first drafts feverishly fast, and then I spend years editing. It's not that sentence-by-sentence perfectionist technique some writers I admire use. I need to see the thing, in some form, and then work with it over and over and over until it makes sense to me - until its concerns approach me, until its themes come to my attention. At that editing stage, the story picks itself and it's just up to me to see it, to find it. If I've done a good job, what it all means will force me to confront it in further edits.

9/11 was just an enormous event in so many senses of the word - I mean, we are still in the "post-9/11 era" and perhaps will be forever? Sometimes it seems like it. It was such a monstrous act of imagination over anything else - the actual fatalities, while awful, were not what distinguished the event from others.

I love outsider stories. And I also like a lot of genre fiction, too. So I wanted to write a literary book that flirted with thriller and fantasy and even science fiction. I wanted the coming-of-age story and the love story to be about "outsiderdom" - one of the themes I am most interested in.

Because for me to go fully experimental, it would turn into an artist book actually. And I'm not opposed to that. But I wanted to toy with the conventions of traditional narrative and sometimes to do that all the way, you have to actually utilize traditional narrative, I think - or it's one way to do it.

Time kept on and on like the cheapest toilet paper.

Addiction is a very compelling subject for literature - especially now that it's nearly impossible to come out of adult experience without some addiction - to substances, sure, but also to love, sex, success, failure, power.
