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

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.

  • While the listener experience will vary wildly — and that’s on purpose — all Bonus Chapters will share a set of qualities:

    Short: 30 minutes max, just enough to dip into a storyworld and draw listeners even further into the book.

    Embodied: performed by the author, to spark the specific delight of meeting a writer you love.

    Alive: punctuated by sound from the author’s archives and other untapped sources — an interview fragment, social media post, journal read-aloud, vintage news-reel, audio ripped from video the writer recorded as part of the reporting process, original sound design, etc.

    Additive: faithful enough to the book that the audio experience produces a gorgeous feeling of recognition in a reader who gets to encounter some of the same material, expressed in two ways.

    Scored: featuring a soundtrack to propel the story forward and land moments of emotional impact.

    Insightful: candid talks with the author and behind-the-scenes tidbits that bring fans inside the creative process.

  • Between Lissa and Sharif, we have 30-some years of audio experience, from creating series, to writing and editing, to producing and sound designing. Our work has reached millions of listeners; won awards including Peabody, Murrow, Kennedy, Gracie, Third Coast, IRE, NLGJA, and Pulitzer;) and has been featured on NPR, This American Life, 99% Invisible, Vox Media, Audible, Spotify, and Apple.

  • There is huge, unrealized potential for inventiveness in short-form experimentation with nonfiction audiobooks. We take inspiration from all sorts of sources — the narrative podcasts we know and make, full-cast audio dramatizations in fiction, documentaries of all kinds, and more.

    Bonus Chapter makes it possible for writers to co-create dynamic audio stories that take their books to new heights.

  • If you’re a publisher or author and are interested in creating something together, get in touch!

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.”
