Stephen Leeds: Death & Faxes: Legion

Brandon Sanderson has "leased out" some of his characters to other authors. He puts his name on the cover along with the co-authors that have done most of the writing in a universe that Sanderson created.

There are some mysterious stolen records from the IRS. After investigating it is determined that a sound from a fax machine can impair people. This eventually leads to an investigation of some Iranian scientists that follow the Manichaeism religion and the potential weaponization of sound.

The audiobook gets the style of the Legion books right and does an even better job than Sanderson's own books. Here Leeds fully acknowledges the fictional aspect of his Aspects, yet still must maintain the fiction to carry out his work.
