Author Laura Dave Teases 'The Last Thing He Told Me' Season 2 and Sequel Us: How intentional were you when it came to recapping The Last Thing He Told Me for The First Time I Saw Him? LD: I love sequels that answer questions readers didn't know they were asking. Because of that, I didn't want to spend a lot of time recapping, which is why I made the prologue for this book, the epilogue of the first book. You can get right back in.
