Don't Want to Miss a Thing by Jill Mansell

Dexter Yates loves his fun, care-free London life; he has money, looks and girlfriends galore. But everything changes overnight when his sister dies, leaving him in charge of her eight-month-old daughter Delphi. How is he ever going to cope?

Comic-strip artist Molly Hayes lives in the beautiful Cotswold village of Briarwood. When it comes to relationships, she has a history of choosing all the wrong men. Leaving the city behind, Dex moves to Briarwood - a much better place to work on his parenting skills - and he and Molly become neighbours. There's an undeniable connection between them. But if Dexter's going to adapt, he first has a lot to learn about Molly, about other people's secrets...and about himself. -Goodreads
