"Dick Grayson--the former Robin turned Nightwing turned superspy Agent 37--is back to work at the covert global agency, Spyral. But one question continues to haunt him: Who is Agent Zero, and what does she want with him? Reluctantly aided by his partner, Tiger, Grayson uncovers Agent Zero s origins within the secret lair of Spyral s deceased founder, Doctor Dedalus. In doing so, he and Tiger also become ensnared in a malevolent ouroboros, a self-consuming circle of violence that endlessly connects Spyral to the criminal organization known as Leviathan. Grayson s path soon becomes clear: he must take down Spyral and its director, Helena Bertinelli."--From publisher.
