X-link to the DRM-free thread for the new Wildside Press freebie:
Wildside Press Presents: Discover A New Author: Brian Stableford containing 3 short stories by one of my very favourite authors when it comes to telling great stories about the societal changes occurring from genetic engineering, alongside Nancy Kress.
Also, some new RPG gamebook bundles, and the Humble Star Trek Comics and StoryBundle's Adventure Sci-Fi bundles are expiring soon, if you haven't already decided whether or not you want to pick them up.
