City of Night

Katrina Templair hunts vampires. Any bloodsucker will do, but she's searching for one in particular. She's back in Los Angeles, where her human life ended over four decades ago. Sooner or later, she will get her revenge.
Humans don't believe in vampires. Even after an attack, the average human will replace the supernatural with something mundane in order to get on with their lives. Abbey Marquez is no average human. She remembers not only the attack, but who rescued her and how. Her hero worship of Katrina is a nuisance, but her information regarding a night club where vampires are taking the term "tourist trap" way too literally, is an asset.
The vampires think they are invulnerable, the ultimate predators at the top of the food chain. They're wrong.
When Katrina gave up her human life, she became more than a myth. She became sunlight incarnate.
She became an Odonata.

City of Night is the first book in the Odonata vampire series.
