A good chunk of it is both indie and romantic (m/m included, if you're interested).
But there are also some pretty good sfnal offerings in there, including a complete novella collection of Ursula K. Le Guin from Saga Press, and also some Ken Liu and Stephen Baxter & Alistair Reynolds, Kameron Hurley, shorts collections from Kim Stanley Robinson & Elizabeth Hand and others via specialty publisher PM Press (who were pretty generous with the freebies several years ago), Aurora Award-winning Canadian author Douglas Smith (
ISFDB), Tiptree Award-winning Finnish author Johanna Sinisalo (
ISFDB,
Wikipedia), and a very funny backlist science fiction mystery adventure novel (previously from DAW) by John Zakour (
ISFDB,
Wikipedia) & Lawrence Ganem (
ISFDB), 1st in his John Zachary Nixon series starring the future planet's last P. I., which I
read a long time ago and enjoyed, and wish they'd get the other books out since apparently DAW is no longer offering them.
ETA: there's also an illustrated story which won the 1995 for Best Original Artwork, by artist Brian Froud (
ISFDB,
Wikipedia), out from Abrams Media. And early sfnal classics from the late literary author J. G. Ballard (
ISFDB,
Wikipedia) and Russian science fiction author Arkady Strugatsky (
