What to read after Bloodstone?

They call it Deadtown: the city's quarantined section for its inhuman and undead residents. Most humans stay far from its borders - but Victory Vaughn, Boston's only professional demon slayer, isn't exactly human... Boston's diverse South End is known for its architecture and great restaurants, not its body count. So when mutilated human corpses begin turning up in the area, the entire city takes notice. The killer-dubbed the South End Reaper-uses a curved blade for his grisly work. And even though there's no real evidence pointing to a paranormal culprit, the deaths are straining the already-tense relations between Boston's human and inhuman residents. As the bodies pile up, Vicky, her formidable aunt, Mab, and her werewolf boyfriend, Kane investigate, only to find that the creature behind the carnage is after something much more than blood...
