The Last Thing He Told Me Season 2 premiered on February 20, but is it based on a book like the first season? Season 1 had Laura Dave’s novel of the same name to use as source material, but her sequel, The First Time I Saw Him, wasn’t released until January 2026, just a month before the Season 2 premiere.

Season 2 is very loosely based on this sequel novel, as the show’s writers had the first 100 pages from Dave when they started working on the script. “What was very exciting and unconventional was that the audience response to Season 1 was so huge that fans clearly wanted a continuation of the story,” executive producer Lauren Neustadter tells TV Insider. “They wanted a Season 2, and the conversation that we had was Laura really wanted to write the novel, and the audience was not going to want to wait that long.”
