Waning (The Lunar Phases Book 1)

Upon Luanna’s return to her hometown of Tosle, she realises that the only thing to change over the past four hundred years are its inhabitants. It is there that, after a century of flitting from place to place, she finally meets someone worth settling down with.
For the first time in decades, she feels normal again, until their differences begin to take a toll on their marriage. But, just as things are about to hit breaking point, an accident forces her to remember how fragile humans are.
Now Hazel Turner, her best friend, is the only person left standing between Luna and a bloody massacre.
How is she supposed to stop a four-hundred-year-old vampire from losing control and giving in to her baser instincts?
After all, she’s only human.
