I’ve mentioned Kelley Armstrong here once or twice before; she has 4 published books and has deals done for 9 with various publishers, so she is kinda popular. Anyways, every year she writes an e-serial, and has recently finished this years; Beginnings. It is on her website in various formats if you wanna go read.
Course the ending isn’t very satisfying unless you’ve read the first book Bitten. But it’ll give you a good idea of her style
Next year she will be doing a series of short stories online dealing with different characters in her Otherworld ‘verse.
