So I got some good news the other day. ;D Yup, Loose Cannon is going to be available as a paperback, too!
Don't panic if you've noticed that the date is different than you'd expected; the ebook will still be released on April 3. Due to some slight shipping delays, the paperback will be released on April 4th from both Amazon and Barnes and Noble (websites only, no stores). You can pre-order the paperback from Amazon now.
