I wrote two non-fiction handbooks and co-wrote another with Jamie Engle.
Perilous Pauline's Multiformat (Sony/Nook/Kindle) from Fictionwise.
Perilous Pauline's Books at Barnes and Noble (now including NOOK!), at Amazon, at All About Romance (ARe), and at Omnilit. Also available in iTunes in the iBookstore (access through iBooks app).
