A twisted tale told by Harley Quinn herself, as only Harley can tell it. When Gotham's most nefariously narcissistic villain, Roman Sionis, and his zealous right-hand, Zsasz, put a target on a young girl named Cass, the city is turned upside down looking for her. Harley, Huntress, Black Canary and Renee Montoya's paths collide, and the unlikely foursome has no choice but to team up to take Roman down.

Task force X has been in constant service, but also must constantly recruit new members as the Suicide Squad lives up to its name. For a mission on the island of Corto Maltese, only Waller knows what Colonel Flag and his cons from Belle Reve will face, but team is in for a surprise -- and an enemy -- of epic proportions.
