Nocturne

It's Mardi Gras, cher, but this year le bon temps kick off with murder…
For generations, the White Monks have treated the vampire Thaddeus Dupont as a weapon in their battle against demons. However, when a prominent matron drops dead at a party, Thaddeus and his lover Sarasija are asked to find her killer. Their investigation leads them to an old southern family with connections everywhere: Louisiana politics, big business, the Church, and an organization just as secret as the White Monks.

Meanwhile, an esoteric text containing spells for demon-summoning has disappeared, Thaddeus is losing control of le monstre, and Sara is troubled by disturbing dreams. These nightmares could be a side-effect of dating a vampire, or they could be a remnant of his brush with evil. As the nights wear on, Sara fears they are a manifestation of something darker - a secret that could destroy his relationship with Thaddeus.
