X-link to the DRM-free thread for the new Humble Bundle:
Humble Book Bundle A Galaxy of Stars in Sci-Fi & Fantasy presented by Open Road has an excellent selection, actually containing what look like some Houghton Mifflin Harcourt books as well. There's Ursula K. Le Guin, Harlan Ellison, R. A. MacAvoy (a charming time travel adventure to early medieval Ireland which I rather liked when I bought it via Fictionwise a long time ago), Poul Anderson, Robert McCammon, Patricia C. Wrede (what looks the entirety of her Lyra quintet, if you've missed the previous sales on the omnibus or it wasn't available in your region), Theodore Sturgeon (apparently geo-restricted to US only), Elizabeth Briggs, Octavia E. Butler, and more.
A few repeats (I'm pretty sure I already have the Butler (ETA: only the 1st of the quartet offered has been bundled before; the rest are new) and some McCammon from previous ORM bundles), but plenty of new-to-bundle looking stuff, although a lot of it has been discounted in the US before, and some of it was likely in their US-only giveaway a while ago. But aside from the geo-restrictions on the Sturgeon, it's a really good offer for international Gentle Readers who don't travel much.
