The Last Island

Bestselling author of 1861: The Civil War Awakening (Knopf / Vintage)
Publication will coincide with the premiere of a feature-length National Geographic documentary about North Sentinel Island, the first such film ever produced. The film, whose working title is "The Last Mission," is slated for early 2023 release both online and in theaters. Its filmmakers have recorded more than six hours of interviews with Adam Goodheart, who is serving as a consultant on the production. They also plan to include photographs and journal entries chronicling his 1998 journey to the island.
Apart from John Allen Chau - who did not live to tell the tale - Adam Goodheart is the only American known to have visited North Sentinel.
North Sentinel Island has what might be called a worldwide fan base. Amidst a global culture of hyperconnectivity, the Sentinelese are portrayed as the lone holdouts. Especially since the death of John Allen Chau in 2018, millions of people around the world have been fascinated with this remote tribe. A few statistics:
YouTube videos about North Sentinel Island have garnered a cumulative total of more than 106 million views.
Hundreds of posts about North Sentinel Island on Twitter, Instagram, Reddit and Quora have drawn millions of views, comments, and likes. An Instagram post just six weeks ago drew over 256,000 likes.
Interest has not stopped since John Chau's death. A query on Quora last August about the island has garnered over 200,000 views in the past six months. ("Why don't the Sentinelese people try to discover the outside world, and why do they never leave their island? Have they ever been to South Andaman island which is just 10 mi away?").
The death of John Allen Chau drew intense press coverage in almost every major news outlet. For instance, the New York Times ran seven stories about the incident in just a week, including a front-page feature.
 
Yet there has never been any book published about North Sentinel Island. The Last Island will be the first of its kind.
