Think about the worst moment in your life. A moment that changed irrevocably everything you've ever known. Would you take that moment back?
What if that moment offers you a different life, allows you to do things you would never do otherwise? Meet people you would never know?
Think again.
That one moment transforms the lives of a dozen people, each keeping a secret they can never expose. A single thread ties them together. Inextricably and forever. Cut it, and someone dies.
