A Superhero for Christmas by H.L. Burke
On the last days of Christmas I read this. . .
A superhero in a fight when his powers fail. When Christmas is rolling around, he decides to go to the small town where he spent summers with his grandfather, and decide what to do with the house his grandfather left him.
Meanwhile, a woman works in the store there, having broken up with her boyfriend on bad terms. Her working with him as a journalist also left her nothing.
A lightsome romance with some superheroics.
