Darkness Rising - Number 2 in series

The sexy, thrilling adventures continue in bestselling author Keri Arthur's new Dark Angels series, starring half-werewolf/half-Aedh Risa Jones. Risa will go to any lengths to avenge her mother's murder - even if it means making a pact with the most evil vampire she's ever met. Lethal and powerful, Madeline Hunter is leader of the vampire council and will put her resources behind finding the killer - for a price.
The venerable vampire requires the assistance of Risa's psychic powers. Quid pro quo. Someone - or something - is targeting the elders of the local council, cursing the immortal vampires to rapidly age, sink into madness and die. Risa must track down the vengeful being responsible. But Risa's father, a rogue Aedh priest, also enlists her in a dangerous mission. And not even the great Madeline Hunter may be able to protect her from the shadowy forces that desire nothing less than Risa's destruction.
