Kirk and Spock are on a strange planet with no weapons, no communicators, and no clue what the hell is happening. They have no way of knowing that Spock Prime's life depends on their choices.

You know of those stories where the transporter sends Kirk or Spock careening into another universe where everything is weird? Well, this isn't one of those. No, this is the story where the transporter makes everything weird in its own universe. Though it skipped the gender-change trope. No, this is a new one. Add on sex, political negotiations, angry admirals, and an unexpected marriage and things get quite complicated.

Sometimes the other Vulcans wonder how Spock managed to obtain such an exotic bondmate, and sometimes Spock wonders himself.

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.
