Everyone knows Robin, Batman's little bird. Not everyone knows he has a second protégé, another bird.
Sileas, or Sparrow, grew up in Jack Haly's travelling circus together with Dick. She stayed behind when Dick left to live with Bruce Wayne.
Years later, the circus is in Gotham city again. Her mother passed in those years and she didn't have anyone else, so she stayed with Jack Haly's circus. But when Bruce Wayne makes her an offer she can't resist, Sileas' life changes.
This is the story of how Sileas changed to Sparrow.
First five/six chapters are prior to season one of the series. After that, it follows the storyline, with Sileas in it.
