Fated, Always, Laid Open and Cake are all novellas. They are too short to go to print. Sometimes publishers put novellas with other short works by the same author or with other novellas from different authors into print anthologies. At this point, I do not know of any plans for the books I mentioned going to print.
My digital first titles from Samhain (if they are long enough) will go to print six months after they release in digital formats.
My Carina books are a project by project thing. Goddess With a Blade is releasing in mass market paperback in December 2013 but I don’t know of any plans for Second Chances.
