I'm the author of the ASHFALL three-and-a-half-ology: ASHFALL, ASHEN WINTER, SUNRISE, and DARLA'S STORY.
I donated the first ever complete set of ASHFALL books to my local library foundation for their auction. Want to read SUNRISE way before 3/17/14 when it releases to the general public? Bid here. (Scroll down to item #506)
