"After being declared criminally insane, the world's deadliest assassin, Deathstroke, is committed to the infamous Arkham Asylum! It isn't long before the hunter becomes the hunted as Slade, powerless and weaponless, is targeted by some of Gotham City's most wanted. But after initially mocking and contravening the system meant to help him, Deathstroke learns that his only hope for survival may be to confront his own inner demons. But has Slade really lost his mind? Is an alien invasion really imminent? And just who is this impostor masquerading as Slade on the outside? Lots of questions, and Slade may not survive long enough to answer them all."--
