The Pariah Child Evley's Descent. The Pariah Child, #4

Bolanile is dead. Evley's last gift to her was to ensure she was buried in a red dress--her favorite color. But without her the manor feels much emptier, Orisa and Kwento much more distant, and the world a bit more gray. Still, Evley's managing. He's managing quite well actually, despite what everyone else may think with their constant pestering. Life isn't perfect but it's moving on. Then Orisa begins vomiting dirt while Kwento begins cutting away at his flesh.
And no one's sure why. Things only take a turn for the worse when a family of gargoyles ambushes Evley in his office at the Department of Domestic & Exotic Beasts. They want him to aid them in preventing a human caravan of Lyricans from opening a portal and crossing over to Earth. But the portals are sealed and humans can't open them. Not alone at least, not until they receive help from a woman in a red dress...
In the fourth book of the Pariah Child series, gargoyles, the undead, and witches are all in need. And Evley's the only one who can help them.
