Spring 1986, Oxford. Rachel is engaged to handsome author Jonny, and with a dream to open her own art gallery. It's everything she wished for. So when she meets candid and carefree American artist Gabe at a party and feels a familiar spark, she knows she needs to resist. But there's no denying the lure of the spontaneous, wildly adventurous existence Gabe seems to offer. And how can Rachel focus on the life she thought she wanted, when she can't help imagining the alternative? One thing's for certain: Gabe is more than a minor character in Rachel's life. And as their paths intersect over seasons and decades, each meeting presents Rachel with a choice that could alter everything, and she has to wonder whether the life story she once fought for is the version she's meant to be living...
