X-link to the DRM-free thread for a new StoryBundle:
The Escapist Bundle curated by one of the editors at WMG which produces the Fiction River anthologies contains a mix of backlist and new novels with the theme of escapism, which apparently works out to be mainly sfnal works (and one lone mystery/crime thriller). There's an anthology of pulp-styled stories, three collections of previously-published shorts by award-nominated authors Cat Rambo, Kristine Kathryn Rusch, and Canadian author Rebecca M. Senese, and several new-ish novels by established writers.
And for fans of the BattleTech MilSF gaming franchise, Bundle of Holding is offering the RPG tabletop gamebooks for that.
