Trustworthy as ever.
Tricks and twists at every turn.
Troublesome fun for one to learn.

Rachel has something she called evil inside her. She met Whisper. Together they went to Detective Dick Grayson for help. Then they met Kory. After that they met Gar. Whisper won't talk at all. Dick used to be Robin but is now a Detroit Police Detective. Kory can't remember anything about herself but can harness the power of the sun. Gar can transform into a green tiger. Together they make an unlikely team determined to help Rachel and Whisper find themselves.
Whisper, well that's what everyone decided to call her all because she doesn't know her real name nor did she talk to them. The people who raised her abused, tortured and experimented on her. She doesn't know what having a real family feels like. To her friends that she didn't trust she was the quiet little girl they had named Whisper. To CADMUS she was Subject Acrobat.
Would Dick's life change forever when he learned that his mother had been 7 months pregnant with a baby girl the night she died. And that the paramedics had been able to get the baby out and save her life. Yeah, that was great and all, except the fact that she was sent to a different family. Now all he has to do is find her.
