The Brightest Star in the Sky by Marian Keyes

Second Hand 

"Novel follows seven neighbors whose lives become entangled when a sassy and prescient spirit pays a visit to their Dublin townhouse with the intent of changing at least one of their lives. But what will this metamorphosis be and who will the sprite choose? There's Matt and Maeve, the newlyweds struggling to overcome the first obstacle in their storybook romance; Lydia, the brassy but vulnerable cabbie; Katie, the just-turned-forty PR executive searching for a more gratifying life; and the eldest resident, Jemima, currently playing hostess to her son Fionn, who is in town to star as the hunky gardener in a hot new television show. Keyes's universal themes and appealing characters have made her an international phenomenon, and are sure to conquer a wider American audience. With The Brightest Star in the Sky, she delivers another satisfying story charming in its wit and surprising in its depth."--Publisher.
