I'm not exactly a superfan, but I've read most of the books. Without Remorse is the root of the entire Jack Ryan series. Half the Ryan characters make their first appearance there. Even Jack Ryan's father is in it, as the detective who pursues Kelly. Most of the subsequent Ryan books contain somewhere a reference back to the events in Without Remorse.
