We collaborate with authors to create immersive excerpts of their nonfiction audiobooks, brought to life with voice, score, and sound design.

Our Pilot

Oprah Winfrey Feminism

From Leila C. Nadir’s forthcoming book, Afghan Americana: An Intimate Geopolitical Memoir.

Our Story

Bonus Chapter is an experiment.

Full-length nonfiction audiobooks can be amazing. But what if you also got a short audio teaser that fully exploits the sonic medium, plunging your established audience (and potentially a whole new audience) into your story’s world?

Send it to sites, podcasts, radio programs. Play it during book tours.

Bonus Chapter is a way to share your book in a whole new dimension.

The John D. and Catherine T. MacArthur foundation generously funded our pilot.

“Collaborating with you all awakened my awareness to a layer of experience — like a sonic ecosystem within my writing — that I hadn’t imagined before.”

-Leila Nadir

Our Collaborators

Leila C. Nadir

Leila Christine Nadir is an Afghan-American artist and writer whose work appears in literary and scholarly journals; in museums and galleries; and in forests, classrooms, and kitchens. She explores intersections of ecological destruction, colonial traumas, immigration upheavals, and family violence and how individuals and communities rebuild and grow after their worlds fall apart.

Leila’s Bonus Chapter is an excerpt of her intimate geopolitical memoir-in-progress about the wars that rage within families, in nations, and across the planet.
