    I’ve been a fan since you started with Tom Clancy and found a couple of signed copies of your books at The Poison Pen in Phoenix two years ago.

    I linked to your blog from Amazon as I was looking for your upcoming releases. Reading the post on your tour, I’m unable to read the tour dates and locations. Would you mind sending me the details and perhaps posting a higher res image on your blog page?

    I travel quite a bit and live in Huntsville, AL, if the opportunity exists I’d like to drop in on one of your events and chat.

    Will Mission Critical be produced in an MP3 CD format similar to the first 7 books in the series ? I have listened to all of the prior books on MP3 CDs but I do not belong to the Audible subscription service .
