Chimera Falls by Pierre Roustan (Paperback-New)

Chimera Falls is a dark, dramatic horror sequel to his vampiric Christian suspense thriller, The Cain Letters. It is the second book in The Divine Covenant series. 

The story follows Alexandra Glade, an infamous vampire hunter for the Berith Lochem. Despite her victory in the previous book, Alexandra is more isolated than ever; she has lost her team and her ally, Kyan, has been captured and tortured by an unknown enemy.

As she searches for Kyan, she must navigate a world increasingly filled with "real" demons—entities far deadlier than the revenants she has spent years killing. Her primary lead is a mysterious word, MALUMUNUS. Meanwhile, Cardinal Felix Delgado has retreated into hiding with the dangerous Cain Letters, and a dark spirit known as the Chimera offers Alexandra potential answers, though at a terrifying cost.
