Cassandra Palmer Series by Karen Chance

Cassie Palmer, a powerful clairvoyant who works part-time at an Atlanta club reading Tarot cards, is finding it difficult to escape her past. Orphaned at a young age and brought up by the undead, Cassie has the ability to communicate with the spirit realm, and her powers were abused time and time again by a ruthless master vampire named Tony. It's been three years since Cassie -- a self-described "ghost magnet" -- has been free of the centuries-old bloodsucker, but now he's back and eager to reclaim his human possession. Forced to turn to the Senate (a group of "really old vamps" who make laws for the supernatural community) for protection, Cassie is thrown into a complex conflict where control of the entire supernatural world is at stake. Rasputin (yes, the Mad Monk himself), a power-hungry vampire, is killing off the Senate members one by one. Aided by some impressive allies -- including Dracula's older brother, Mircea -- Cassie must use everything in her paranormal arsenal to fight the encroaching evil -- and somehow stay alive 

Clairvoyant Cassie Plamer has inherited new magical powers-including the ability to travel through time. But it's a whole lot of responsibility she'd rather not have. Now she's the most popular girl in town, as an assortment of vamps, fey, and mages try to convince, force, or seduce her-and her magic-over to their side. But one particular master vampire didn't ask what Cassie wanted before putting a claim on her. He had a spell cast that binds her to him, and now she doesn't know if what she feels for him is real-or imagined...

Cassandra Palmer may be the world's chief clairvoyant, but she's still magically bound to a master vampire. Only an ancient book called the Codex Merlini possesses the incantation to free Cassie; but harnessing its limitless power could endanger the world.

Cassie Palmer has strawberry blonde hair, blue eyes, and a 9-millimeter Beretta. In addition to those impressive attributes, she also possesses the power of clairvoyance. Neither beauty, gifts, nor weapons, however, can protect her completely against the powers of the self-styled god Apollo. In this fourth series novel, Cassie faces down her creator once and for all. A sexy, fast-moving fantasy series that continues to win enthusiasts.

Cassandra Palmer recently defeated a god, which you'd think would buy a girl a little time off. But it doesn't work that way when your job description is Pythia-the world's chief clairvoyant. Cassie is busier than ever, trying to learn about her power, preparing for her upcoming coronation, and figuring out her relationship with the enigmatic sexy master vampire, Mircea.

But someone doesn't want Cassie to become Pythia, and is willing to go to any lengths to make sure the coronation ceremony never happens- including attacking her mother before Cassie is even born.
