RE: Addiction and Recovery

This is an interesting 'bad habit', being late. It's hard to break, for sure. You describe Grace's challenge well. One element lacking in the story is the gift. What was it? Authors often leave off an ending like that, thinking mystery is intriguing. It's not. The gift, readers would expect, might have been related to time in some way. That would have been an appropriate ending. But, of course, any gift that satisfied your idea of an ending would have been fine.

It's never a good idea to leave readers frustrated :) Takes away from the quality of the story, which in this case is good.
