The Gorging of Souls - Origin Codex, #2

Light and Dark, Life and Death. Eight and a half months after Detective Ann Logan and seven-year-old Maggie Hart prevented Yaldabaoth from unleashing terror upon the world, all is quiet in Harmony, Colorado. But when Teresa Hart escapes from Mountain View Mental Hospital, Maggie's perpetual nightmares intensify, and the mysterious marks that link Maggie and Ann burn to life, signaling the presence of a new evil-or the return of an old one.
The ancient war between the servants of darkness and the servants of light is far from over. Once again Maggie and Ann, bound together by destiny, hold the space between the delicate balance of life as we know it and eternal horror. The fate of humanity hangs in the balance. On the filthy tattered sofa in the abandoned funeral home at the edge of Harmony, something evil has pushed its way into the world.
And it is hungry.
