The 2-part "Leviathan" story kicks off from guest writer Chris Yost (RED ROBIN) as The Huntress finds herself in an unusual position - the responsible one. Because when Huntress hunts down a violent new criminal, she finds herself stuck with a violent, loose cannon of a partner on the case - the Man-Bat! And in a special story from Mike Benson (Deadpool: Suicide Kings, Moon Knight), Batman and Robin uncover a sinister plot involving dozens of Gotham City's young runaways. Is Arkham Asylum escapee Humpty Dumpty at the center of the scheme - or is he just the tip of an even more dangerous iceberg?
