"We're both trapped in this nut-house, Harleen. Only difference is, you're on the payroll." An act of kindness towards Arkham's most notorious inmate sparks a downward spiral which will send Harleen Quinzel's life spinning out of control. But in games of love and madness, how far can you go before you break? An in-depth take on Harley's origin story, with mature themes.

When Amanda Waller had first started gathering up bad guys to become a part of her plan. Harley Quinn had never been a part of that plan. Waller was always after one person. One person, she knew she could never control. One person, she knew who on a whim would sabotage her entire operation and one person she knew she had to have on her team. The king of Gotham himself, the Joker.
