Johnny navigates the secret Faerie courts, dream demons, and otherworldly outlaws threatening the city's unsuspecting mortals. When a string of gruesome murders and a looming apocalyptic plot threaten to shatter the boundaries between the Fae and mortal worlds, Johnny must confront his own inner demons and forge uneasy alliances to unravel the mystery before the city succumbs to chaos. With the help of his network of contacts, including the alluring witch Áine Moonwhisper and the ghoulish Wights, Johnny delves deeper into the mystery, uncovering a sinister plot orchestrated by the nightmare king Somnus. The investigation leads him to the heart of the Oneiros, where he discovers a plan to resurrect the ancient Devourer, a primordial entity capable of consuming both the Dreaming and the Waking World. With the fate of New York City and the entire world hanging in the balance, Johnny must forge uneasy alliances, battle his way through the nightmare realm, and ultimately face off against Somnus himself.
