X-link to the DRM-free thread for new Humble Bundle and StoryBundle offerings:
Military Horror Bundle curated by small publisher Cohesion Press contains sfnal hybrid tales of soldiers fighting monsters, with both military sci-fi and fantasy ranging throughout space and time, with a mix of newly-written novels (including a MilSF series which from its covers, has cyborg dinosaurs in it, including what the blurb praise says is "an armored T-rex with a friggin' railgun") and themed short story anthologies. Contributors include Hugo & Nebula-winner Mike Resnick and Stoker Award-winner Jonathan Maberry.
Humble RPG Book Bundle Fiction Faves contains selected titles from the officially licensed tabletop roleplaying games for popular sf/fantasy series such as A Song of Ice and Fire, The Laundry Files, and more. These are enough to get you started with the rules and the campaigns at a low cost (apparently gaming books are normally quite pricey) and some of the guides also serve as a handy semi-encyclopedic compilation of useful info about the books' settings, as good as an easily-consultable fan wiki.
