The body of Wade Franks hangs from a gargoyle in Old Town, bathed in the harsh glow of the spring Blood moon. Terrible, bloody wounds cover his body and it's clear he didn't give up without a fight. But a fight against who...or what? Detective Raven Storm is assigned to uncover the truth behind Franks' death, chalking up another 'unsolvable' case for the Chicago Police. Together with her partner Rupert Levac, Raven embarks on an investigation that leads deeper into terrifying darkness than ever before, into a sanctuary of evil older than Chicago itself where she will need all her wits, training and vampiric heritage to survive. A Storm is rising beneath the Blood moon. And hell is coming with her.
