Some of my favorite stories have started with an alternate beginning. I just love the exploration of L&C falling for each other in a different sort of environment, and seeing how Superman will fit into story. Makes for a great read....
I'm still reading
Trusting Me, Trusting You by Female Hawk (which I absolutely love!), but another of my favorite alternate beginning stories is
Field of Dreams by Caroline K.
Hope someone runs with the idea!
