It's a long way back to happily ever after.

Sean and Kyle have enjoyed six perfect years of what their friends called a "disgustingly happy" relationship. But what happens one sunny Tuesday morning in October might be more than even the most loving couple can survive.

When the bell rings that morning in chemistry teacher Sean Farnham's first-period class, a terrifying sound fills the halls – gunshots. Without considering the consequences, Sean runs to tackle the shooter, sustaining a bullet wound to his leg. Despite his actions, he is unable to save the lives of the principal and two students.

Architect Kyle DeRusso hears about the shooting on the radio, and in the flash of an instant finds his life irrevocably altered. Everything – especially his heart – hangs suspended in a nightmare until he finds out Sean is alive. It doesn't matter that Sean will be left with a permanent limp. Kyle's just relieved the worst is over.

Or is it? Putting that day behind them isn't as simple as it sounds. As Sean struggles to make something positive out of the tragedy, Kyle fights to save their relationship from the dangers of publicity – and Sean's unwillingness to face how the crisis has changed him.
