As of mid-2015, I have introduced ASK MAX!, the hip new way to ask me stuff. This is where you type something into the speech bubble on the front page and I post a reply in blog form.
This way is better for me because I get to answer your question and produce content for the site.
But if you have something private, you'd better email me. This is less likely to get an answer, I'm very sorry to say. I used to reply to all email, and it was great: I liked getting it, I liked writing back, and I loved hearing that someone had their car broken into and the only thing the thief took was a copy of Jennifer Government. But this took a lot of time, so I had to stop.
I am sorry about this, because before I was published I wrote to an author once and when she e-mailed back, it was just about the coolest thing ever.
My email address: My first name followed by an underscore and my surname @maxbarry.com
Please put the word "duck" in your subject title, e.g. "[duck] Why you're an idiot." I get lots of spam and this prevents your message from being accidentally filtered.
