X-link to the DRM-free thread for some Humble Bundle additions with sfnal tie-ins:
Last week's
Humble Book Bundle Puzzles presented by Lone Shark Games & Friends, containing mostly crossword puzzle books, has added to the $15 top tier an audiobook novel in a faux-Victorian supernatural Choose Your Own Adventure mystery style narrated by Star Trek actor Wil Wheaton, if you happen to be a fan of his and also like solving puzzles. The ebook novel (PDF format since it incorporates puzzles into the text) is already included in the middle tier. ETA: included in the audiobook download are three soundtrack albums, one of which is normally sold separately. This was some sort of popular former Kickstarter project.
And there's also a new offering for the gamebooks and some merchandise for the popular
Vampire: the Masquerade (
Wikipedia) RPG/LARP setting from White Wolf, which was the basis for the short-lived supernatural TV show
Kindred: The Embraced (
Wikipedia), if you happen to be a fan of either of those, with what appears to be an illustrated prose storybook at the middle tier.
