Tom Clancy has a new novel coming out this year. That's all I know. With any luck it'll be set in the Ryanverse and he'll be continuing the story. Then again, he wrote Red Storm Rising as having nothing to do with the Ryanverse and it is probably one of his more gripping novels.
Half of me hopes that it'll be an all new story and half of me hopes that it'll be Ryanverse. Half of the half (so a quarter) that's going with the Ryanverse wants to see where he goes with Jack Ryan, Jr. The last quarter wants Jack Ryan himself, the former president, to take action. And somewhere in all of that I want more John Clark/Ding Chavez/Rainbow.
