Hello Mr. Burke,
I cannot believe I haven't come across your books before. I am a New Orleans native and also a fiction writer. I just had my first novel UNHINGED published by Medallion press, I can officially call myself a "author." ha ha.
Anyway, I purchased The Tin Roof Blowdown specifically because it was set during Katrina. I am halfway through and loving it. I now plan on starting my JLB collection. I have spent the last year working on a fictional crime thriller based on true accounts that happened to a paramedic in the days before, during, and after Katrina in New Orleans. This manuscript has landed me an agent in New York and we are now discussing final edits. I've let others read it and they are blown away.
I don't contact other authors and have never asked one to read my stuff (except Anne Rice, but that's a long story), but a looksie from an author who has written about the same subject is rare in this case. I don't feel there are any legal issues, since I already have representation. Again, I am from New Orleans, so you can understand that I would be naive enough to think you might want to.
If not, don't sweat it. I completely understand and that won't change my mind on reading all your work. Hopefully, one day we might meet up at a conference or something.
