Every year, Smashwords holds a site-wide promotion they call the summer/winter sale (because some of us are in summer and some of us are in winter). So until July 31, 2012, all of my books are half off at Smashwords!
Biohazard (now $1.50)
The Jester’s Apprentice (now $2)
Dead Locked (now $2)
You can download all of my books in whatever digital format you prefer, including PDF. And be sure to check out books by other authors participating in the sale!
