Humble's new Iconic Sci-Fi Audiobooks Bundle deal is perfect for anyone craving some science fiction listening material. The bundle includes up to 20 sci-fi audiobooks, including enduring classics and modern best-sellers.

Like other Humble bundles, this audiobook pack is a pay-what-you-want deal. If you drop just $1, you get three audiobooks, including the first book in Larry Niven's award-winning Ringworld series, which is widely viewed as one of the best series and has proven highly influential to other popular sci-fi properties, including Halo. You also get The Runelords: The Sum of All Men by David Fairland and Hell Divers, the first book in Nicholas Sansbury Smith's long-running post-apocalyptic saga.

Upping your payment to at least $10 unlocks four more audiobooks for a total of seven titles, including sequels to some of the $1 tier's titles like Hell Divers 2 Ghosts and The Ringworld Engineers, along with Ice Prophet by William R Forstchen and The Sharing Knife Vol. 1, Beguilement by Lois MacMaster Bujold.
