It's an all
audio novella collection that John Scalzi, Elizabeth Bear (I guess Anarkey's in), Jay Lake, Tobias Buckell, and Karl Schroeder each contributed to. The stories are told in a shared universe.
I'm curious enough. And I think it's pretty cool that the stories are all audio. The only catch for me is that I'm pretty sure Audible still uses DRM, which is a bummer.
