That French Summer by Sienna Waters

Who needs perfection?
Reeling from a very public scandal, Delia Holland takes refuge in a run-down French chateau. She’s determined to stay out of the lime-light, to rebuild her life, and most of all, to be happy. Guillotining her husband would be the icing on the cake, if only she could find him.
After an accident and a surprise breakup, Paris Bennett finds herself alone on her longed-for French vacation. Her characteristically immaculate plans have fallen apart, and she’s barely holding herself together. Plus, the novelty of being Paris in Paris is rapidly starting to wear off.
But when a thunderstorm brings the two together for a night, something begins to sparkle. Delia’s heart starts to fill with happiness again, and Paris suddenly finds that her carefully laid out plans aren’t as necessary as she thought.
Grumpy neighbors, interfering English teachers, a housekeeper who’s more than she seems, a battered car, an even more battered moped, rats and spiders galore, and a chateau that could fall on their heads at any moment come together to prove that the perfect love story doesn’t have to be perfect at all. Sometimes happiness is there for the taking, as long as you can persuade yourself to choose it.
