Core Event
On Saturday, billionaire philanthropist and author MacKenzie Scott announced that she will self-publish a new novel, her third, on the Substack platform. **, is slated to be released serially throughout August. In the brief post accompanying the title page, table of contents, character list and epigraphs, Scott urged readers to “read and subscribe” to the Substack newsletter that shares the manuscript’s name.
Literary Background
Scott’s debut novel, *The Testing of Luther Albright* (2005), earned an American Book Award and appeared on the Los Angeles Times Best-of-the-Year list. Her second novel, *Traps* (2013), was promoted through a series of interviews and a rare Vogue profile. Both books were written after she studied creative writing at Princeton University under Nobel laureate Toni Morrison, who supervised Scott’s senior thesis and remained a mentor through the publication of her first novel.
Philanthropic Context
Since finalizing her divorce from Amazon founder Jeff Bezos in 2019, Scott has given away more than $26 billion to over 2,700 organizations, according to Forbes. In 2025 alone, her charitable vehicle Yield Giving disbursed $7.2 billion—more than the lifetime donations reported for Jeff Bezos and Lauren Sánchez Bezos combined. Forbes estimates her net worth at $33.8 billion and notes that she has donated roughly 46 percent of that wealth, ranking her among the world’s most generous philanthropists.
Official Announcement Details
Scott’s Substack post provided the manuscript’s front matter and a release schedule but offered no plot synopsis or additional commentary. An aide did not respond to requests for further information. The novel’s length is reported as approximately 80,000 words, and the serial format will deliver portions of the text to subscribers each week of August.
Potential Impact
By publishing the novel for free on Substack, Scott extends the same unrestricted-giving philosophy that defines her philanthropy to her literary work. The decision places a high-profile, privately-owned author directly in the public eye after a 13-year publishing hiatus, potentially drawing new readers to both her fiction and her charitable initiatives. Observers note that the free, serial distribution may influence how other authors consider alternative publishing models, especially those with substantial personal resources.
