https://www.fictionpress.com/~vanessaravencroft - Should be published, think it is in the works to be based on postings on FP/etc, and while rough certainly worth reading at the current cost (free).
Straying off into Fantasy have you read the Discworld series? Mostly pretty good. And some wonderful fanfics by "A.A. Pessimal" on fanfiction.net
Cory Doctorow's stuff is good, and Freely available as well. Or print. -
Cory Doctorow's craphound.com | Cory Doctorow's Literary Works I recommend For The Win, Down and Out in the Magic Kingdom, Little Brother and Homeland (as a pair). Most of his other stuff is good too.
