Looking for a trusted co-writer and publishing partner to bring your book to life?

Book co-writing is a deeply collaborative, white-glove process designed for a very small number of projects. Lindsay takes no more than one co-writing client per year.

In this container, Lindsay partners closely with you to shape, write, and bring your book to life — from concept and structure through drafting, refinement, and publishing — while preserving your voice and vision throughout the process.

Best for:

  • Families seeking to bring a meaningful memoir or legacy story to life

  • Writers who want to outsource the majority of the writing process while remaining thoughtfully involved

  • Entrepreneurs, executives, and public figures with limited time who are looking for white-glove, end-to-end support

This offering is intentionally limited and is distinct from Lindsay’s group workshops and shorter programs, which are designed for writers who want to develop their own manuscript with guidance, structure, and accountability.

Investment begins at $60,000 per book.

Case Study: The Almost Twins: A True Story of Courage, Perseverance, and Resilience

By AM Kehoe

Co-written with Lindsay MacMillan

In January 2024, Lindsay MacMillan met with aspiring author A.M. Kehoe, who felt called to bring her family’s memoir to life but felt overwhelmed by the writing, publishing, and logistics required to do so.

Over the next twelve months, Lindsay guided the project from concept to completion, serving as the book’s co-author and lead creative partner while also managing the full publishing process. Together, they shaped a deeply personal family story into a polished, publish-ready book designed to endure as a lasting legacy.

One year later, A.M. Kehoe celebrated a successful book launch and the publication of The Almost Twins — a beautifully produced memoir that will remain part of her family’s story for generations.
