Friends in Low Places by EM Jeanmougin

No one ever said being a Hunter would be easy, but Jasper Craig is finding it much more difficult these days.
Following the events of an eye-opening summer spent in the field, Jasper is back within the walls of St. James Academy – New York City’s world-renowned Hunting agency and training school.
And he’s hating every minute of it.
Unfortunately, the only way out is through, and so, with all eyes on him, Jasper once again rejoins the ranks of Hunters keeping the city “safe” from demonic threat.
But St. James’ dogma has lost its luster for Jasper. Not every demon deserves to die due to their inhumanity. Jasper’s (ex?) boyfriend, Crimson Apocalypse, taught him that.
Speaking of Crimson, when a series of mutilated corpses bearing Jasper’s name begin showing up around town, the Hunters suspect the three-thousand-year-old werespider may be to blame. Even worse, there’s plenty of evidence to support the claim. Only Jasper, who knows the man within the monster, believes otherwise. But can he slip through St. James’ iron-clad grip and catch the real culprit before it’s too late?
