Twilight of the Gods — Denise Verrico

Vampire lovers Mia and Kurt are on the run from their Forbidden Science rival Gaius Lupus. After narrowly escaping the implosion of Genpath Laboratories, Immortyls Mia Disantini and Kurt Eisen go into hiding in a place they think is safe. All too soon they are discovered, and Kurt is captured by Gaius. When he's rescued with the aid of feral child and teen vampires known as sewer rats, Mia witnesses first-hand the charismatic spell her lover casts over these would-be revolutionaries, who vow to join Kurt in his mission to bring down the house of Gaius. Meeting obstacles to government funding to support the research that will one day allow them to walk in the sun, Kurt builds his forces. Mia navigates the minefield of rat politics, where she is distressed to be shunted into the background; viewed merely as an overly ambitious concubine who stands between the beloved "Loki" and his followers. One in particular-the oddly timid but beautiful Arturo, who threatens to sever the deep bond between Mia and Kurt. Will Kurt and Mia defeat Gaius's brutal attacks and realize their dream of a cure for their condition? Will the new order they establish survive betrayal from within? And...will their love adapt to the challenge of a third partner?
