The ninth exhilarating and original Firefly novel tying into the critically acclaimed and fan-beloved series, from creator Joss Whedon, follows Mal, Book and the rest of the crew mounting a madcap heist to untangle themselves from a sinister web of lies on a backwater moon.

It all started with the geese. The Firefly crew is eager to get paid for their latest job, but when payment arrives as a gaggle of geese instead of a purse, their stay on the planet Brome gets an indefinite extension. Don’t matter that the geese will fetch a pretty penny once they get somewhere to sell them. Without coin, they can’t buy fuel, and without fuel, they can’t get off-world. Serenity is stuck.

Luckily the foreman of the local fuel refinery, Lyle Horne, wants to hire them, but not to work in the factory. A philanthropic authority known as The Governess has been kidnapping his workers. Lyle’s fixing to get them back—with the help of Mal and his crew. Only trouble is, Lyle’s got a mysterious past with Shepherd Book, one the preacher ain’t too keen to talk about.

Out of options and out of time, they launch a three-pronged plan: Mal will break into her fortress of an estate to retrieve the workers, Inara and Simon will pose as potential donors to the Governess’s charity as a distraction, and Jayne will stay behind to keep an eye on Lyle. But things never do go smooth, and soon the crew finds they have more than a few geese running amuck on Serenity.
Rosiee Thor began her career as a storyteller by demanding to tell her mother bedtime stories instead of the other way around. She spent her childhood reading by flashlight in the closet until she came out as queer. She lives in Oregon and is the author of Young Adult novels Tarnished Are The Stars and Fire Becomes Her, and the picture book The Meaning of Pride.
