My latest serial, Black Blossom, is now raising funds for e-, print and audiobook versions. We hit our target in less than 24 hours, and now we're into stretch goals:
Black Blossom was my most successful serial to date (and I believe it's my sixth, so the data is becoming slowly more useful). There are too many variables for me to analyze why, but I suspect it's some combination of the setting being a fan favorite; the book itself being a sequel to existing books; offering subscriptions; and offering donation incentives. Whatever the reasons, it made more per month than any other sequel I've offered to date (to the tune of almost twice the amount of the next most popular serial, Spots the Space Marine).
I am curious to see whether serial #7, The Faerie Farmer, will show that the trend is continuing upward, or if it'll show that the setting/book topic is what's driving the numbers. We shall see!
Meanwhile, check out the Kickstarter. Some of the stretch goal prizes are going to be fun.
