An Audible original by Felicia Day is coming this fall, with Neil Gaiman on board as the narrator, Variety reports.

Day, the actor known for her roles on the TV series Buffy the Vampire Slayer, Supernatural, and The Guild, will release Third Eye on Amazon’s audiobook service. Audible calls the comedy “a side-splitting adventure that will keep you on the edge of your seat.”

Third Eye, set in “the magical land of San Francisco,” follows Laurel Pettigrew, a hapless wizard who becomes a pariah after failing to defeat an evil creature named Tybus. She’s loathed by everyone in the realm except for her two roommates, a fairy and a vampire.

The production is written by Day, who also stars as Laurel. Novelist Gaiman (American Gods, Anansi Boys) will narrate; other cast members include actors Wil Wheaton (Star Trek: The Next Generation), Sean Astin (The Goonies), Alan Tudyk (Firefly), and YouTuber LilyPichu. Comedian Jonah Ray (Mystery Science Theater 3000) is the director.

Day, the author of books including You’re Never Weird on the Internet (Almost)and Embrace Your Weird: Face Your Fears and Unleash Creativity, announced the project on Twitter, writing, “When I say that this is the biggest thing I’ve ever worked on, I’m not exaggerating. Like, it’s longer than all the seasons of @theguild combined lol.”

Third Eye is slated for release on Oct. 5.
