It was announced in January 2016 that Stone, Skarlatos and Sadler were working with international correspondent and author Jeffrey E. Stern on a memoir entitled "The 15:17 to Paris". It would feature the events of the 2015 Thalys train attack. A publicist for Perseus Books Group sensationalized their forthcoming memoir as "the gripping true story of a terrorist attack that would have killed more than 500 people if not for their actions, but it is also the story of three American boys, their friendship, and the values we hold dear." David Steinberger, president and chief executive officer of Perseus, said that he was "confident that this is going to be a film. It's extremely cinematic, and there's a lot of interest in the movie." He continued, "based on the material, that this was going to be an important book and one that readers were really going to respond to." The memoir was made available to the public on August 23, 2016, almost a year after the 2015 Thalys train attack. In the acknowledgements, Stone stated that he "give[s] all the credit to God" and made further acknowledgement of his family, friends, the United States Air Force, the citizens of Sacramento and the United States Armed Forces.
