Billy Pilgrim has come unstuck in time, and now you can officially set him down anywhere you want to. Amazon's Kindle Worlds publishing arm is set to add the biggest titles from Kurt Vonnegut — author of sci-fi satires including Slaughterhouse-Five and Cat's Cradle — enabling anyone with a keyboard to write and profit off of stories set inside one of Vonnegut's many worlds. "Billy Pilgrim, unstuck in time, is going to quickly become a Kindle Worlds favorite," Donald Farber of the Vonnegut Trust said in a statement.

Kindle Worlds opened in May in an attempt to both profit from and legitimize fan fiction. To do so, Amazon has had to individually secure the rights to every property that it wants to allow authors to publish fan fiction for. So far, that's largely been composed of lesser-known comic characters and teen favorites like Gossip Girl — Vonnegut distinctly marks the publisher's first venture into classic literary works. Amazon hasn't gone into much detail about how reader response has been, but it says that Kindle Worlds has already published 120 stories in its short two months of existence.
