Double Time (слэш)

Cassino, Italy, December 1943. Special Agent Tony Stark, former Marvels adventurer, is sent to investigate a Cosmic Cube found by the Invaders -- and it's the perfect opportunity for him to rekindle his secret romance with Steve Rogers. But when Hydra attempts to steal the Cube, an inadvertent wish for help leads to the appearance of a Tony from the future of another world: Director Stark of SHIELD. This Tony is a man with a lot on his mind. He refuses to tell them anything about the future, but he seems to know much more than he should about Captain America. And something's happened that's clearly killing him inside, but he's not talking. When Director Stark's failed attempt to return home leads to the unexpected appearance of another visitor from his universe, all the lies come undone. Now there are two wars to fight, and the second one could ruin all of them.
