Lakyn can't imagine life without the stars. Sometimes when she's outside after dark, she uses the sky as a big dot-to-dot slate, writing her name across the sky by connecting the stars with invisible lines. As the years go by and Lakyn grows, so does her love for the stars. She wishes she can reach out and touch them. And one night, her dream comes true.

The Nightingirl follows Lakyn as she drifts into the galaxy and discovers she is a nightingirl. Only a nightingirl has the power to restart a star that has gone dark. She meets an array of friends during her travels and discovers a most unlikely hero.
