Sons of Kane series by Tiffany Allee

Dont Bite the Bridesmaid

Alice Shepard needs one thing: a date for her sister's wedding. And not just any date. A hunk who will make her fiancé rue the day he left her for her best friend. Her drop-dead gorgeous neighbor fits the bill—even if he is a bit quirky and never comes out during the day—and Alice has downed just enough appletinis to ask him. But she makes it quite clear that there will be no funny business. Spending a week on a cruise ship full of humans while sleeping close to his sexy next-door neighbor sounds like a helluva bad idea to vampire Noah Thorpe. But his friends need time to get him out of a shotgun wedding—a vampire bonding that will tie his fate to a female vampire he's never met. And Alice's offer comes at just the right time. What could possibly go wrong?
