Summary: “Mr….Mr. Stark?” the man asked, shaking his head as if to clear it, grip convulsing spasmodically on Tony’s hand.
“That’s me,” Tony responded gruffly. Of course the man recognized him. His face had been everywhere before the whole Iron Man thing and now…well, now…so yeah, totally understandable. Guy was probably thinking of his lawyer’s speed dial number. “Look, ambulance is on its way, okay, so just sit tight. You’re going to be fine.”
“I—I think I missed my date,” the blond man said. And promptly passed out.
Or, how Tony accidentally kidnapped Captain America and then wanted to keep him.

Summary: 18 year old Tony Stark is your typical teenager. Well, except for how he’s the playboy billionaire heir to Stark Industries and working on two PhDs. Oh, and 6 months ago he was kidnapped by - well, no one really knows who. Since his rescue (excuse you, Tony liberated himself), he’s also been keeping a pretty big secret. Here’s a hint: it’s shiny, red and gold, and flies. Tony’s had a productive couple of months, but the fact that his grandfather keeps trying to hire bodyguards for his “safety” is really putting a cramp in his ability to keep his secret superhero identity, well, a secret.
Steve Rogers wakes up in 2015 and finds out that he’s missed 70 years (Oh god, does this mean he’s 94?), a revelation that he handles with much less grace than usual. Mostly, Steve just wants to be Captain America again, but on his own terms and without a lot of fanfare. To fill the time while Steve tries to figure out the best way to resurrect a dead superhero, his good friend Isaac Stark offers him a job: bodyguard to Isaac’s grandson, Tony Stark - who seems to get into a surprising amount of trouble for a teenager. “There’s no better introduction to the 21st century than through Tony,” says Isaac. Somehow, Steve is not reassured.

Summary: Tony Stark resigned his commission in Starfleet five years ago, after a disastrous away mission, and he swore he'd never go back. He just wants to be left alone to build warp engines in peace. But the universe has more in store for him than that, as he discovers when Admiral Fury comes to him with an offer he could never have expected and cannot possibly refuse: first officer and chief engineer aboard the all-new USS Avenger, a starship of Tony's own design. What's more, the Avenger's captain is Steve Rogers, hero of the Earth-Romulan War. Believed dead for over a century, Steve is miraculously alive... and very, very attractive.
But nothing is ever easy for Tony. As he wrestles with his secret desire for his new captain and his not-so-dormant fears, another mission starts to go wrong, and Tony becomes aware that Steve has secrets of his own -- and the truth could change everything.
