Lightning in a Bottle — Barbara Elsborg

Lightning isn't supposed to strike twice, but when the electrifying Erin Markov whirls into Felix's life she gives him more than his destroyed family home to think about. Erin's exciting and unpredictable, in and out of bed, if only he could get her to stop dancing in thunderstorms, rollerblading in the middle of the night, and leaping around on unsafe roofs. Plus she has this annoying habit of biting his neck.
Erin wishes she could remember who she is. The couple who claim to be her parents leave her in a dilapidated stately home with supplies of a revolting energy drink and instructions not to go out in the sun. Then she discovers sculptor Felix living next door, and life becomes "far" more tasty.
