The quickest way to contact me is by email. And that email address — apologies for the tortuous length; I need to do it to frustrate spammers — is “author” at my website, which is called “alexrose” and is suffixed by “dot com”. In other words, type in “author”, then key in the @ symbol, followed by the name of my website.
Or you could just go to my website at www.alexrose.com and navigate to the Bio/Email/Media page.
I run a kind of mirror-blog over at Amazon, whose “Author Central” service is still in beta, or experimental, phase. You can have a look here. It has some kinks, but with any luck, they’ll iron them out before launch.
