Rowan Wayne never expected her life to turn out this way. Born to the Joker under the name "Ace", she was taken into the foster care system when she was four and the Joker dragged her along to his first appearance in Gotham. She was quickly adopted by Bruce Wayne. She grew up knowing him as her Father, and was there when he took in Dick Grayson, and then Jason Todd. When she was sixteen, and Jason was seventeen they began dating. When he was twenty one and her twenty, he went after the Joker, alone. He didn't come home. She scoured the city to find him, but for six months, they heard nothing. Until Bruce was sent a video tape. Rowan was devastated that Jason had been murdered. For five years she tried to recover, and suddenly, Scarecrow begins a complete take over of Gotham City with a mysterious stranger, only called "The Arkham Knight", who seems to know everything about Bruce. And about her. What will she find out as the night progresses? And how will she handle the truth when she finally finds out who the Arkham Knight is? ----------------------------------------------------------------------------------------------------------------------------------- (A/N: Big trigger warning for a gore, violence, and mentions of suicide! I will put trigger warnings on the chapters that require it. I do not own the picture used for the cover, I found it on Google! All rights go to the original owner! And, of course, massive spoiler warning for the game Batman: Arkham Knight!)
