They have the whole summer ahead of them. Is it enough to rekindle the friendship they once shared?

Harriet Greenleaf dreams of spending the summer in a beautiful ancient priory on the Somerset coast with her two best friends — but her dream is bittersweet. On the one hand, it's a chance to reconnect three lives that have drifted apart; on the other, she has a devastating secret to share that will change everything between them forever.

First to arrive is Audrey — the workaholic who's heading for a heart attack unless she slows down and makes time for herself. Then Lisa, the happy-go-lucky flirt who's always struggled to commit to anyone — or anything. Ever the optimist, can Harriet remind them of the joy in their lives and the importance of celebrating good friendship before it's gone?

Through the highs and lows of a long, glorious summer, these three women will rediscover what it means to be there for each other — before they face the hardest of goodbyes.
