An accident

There is this common consensus in TF stories, most of which start from where a story logically has to start: the beginning. So we usually meet our protagonist: a man or a woman who gets a new power. And then we get to watch that character discovering its uses and exploiting the situation while the plot unfolds before us. But how many times have each of us got hooked to a new concept only for that concept to end up cut short after one or two chapters? I'd dare say this is an extremely common predicament in sites like CHYOA, CYOC or Writing.com. The thing is, we all want to know what happens afterwards, when the character finally learns how to properly exploit his/her new capacities and settles down into their new existence. And my idea is to try and write a story starting from that exact same point, or somewhere close to it.
