The Stark Effect

Tony Stark is Earth's slightly misguided sweetheart. He's rich, intelligent, and generally considered as a hero after his brave actions during the Battle of New York.
Steven Strange is a reclusive wizard currently engaged in trying to defend the Earth from a race of mysterious and magically gifted aliens.
When Steven finds himself trapped in a seemingly inexplicable and equally inescapable time loop, their paths collide.
Will Steven be able to escape this curse, and why does fate always seem to take him back to a man he has no connection with?
