The tide that kept time
Mara counted the bells from the harbour, the way her mother had, and knew before the seventh that the boat would not come in tonight.
She lit the lamp anyway. Somewhere past the breakwater, a light answered hers, low and patient, as if it had been waiting years for someone to ask.

A note from the maker
Hi, I'm Prasanna
I've kept a notebook of story ideas since I was eleven. Most of them never got past the first line. I built Katha for two kinds of evenings: the ones where you want to disappear into someone else's book, and the ones where you finally want to start your own. Katha gives you a first scene to push against. Everything after that is yours.
