Marnie Fairchild is the brains and talent behind Wish & Co., a boutique store that offers a bespoke gift-buying service to wealthy clients with complicated lives. Brian Charlesworth is Marnie’s most prized customer, and today she’s wrapping the perfect anniversary gift for his wife, Suzanne…and a birthday present for his mistress, Leona. For years, Marnie has had her heart set on moving Wish & Co. to the historic shopfront once owned by her grandfather. When the chance to bid for the property unexpectedly arises, a distracted Marnie makes an uncharacteristic mistake. Soon Brian is in a fight to rescue his marriage, and Marnie is scrabbling to keep her dreams alive. The last thing she needs is to fall for Brian and Suzanne’s gorgeous son, Luke.

Concert pianist Diana is finally ready to marry her longtime fiance, Arie; she’s even composing a beautiful love song for him, and finishes it while on tour. Before she can play it for him, though, tragedy strikes --- and Diana is lost to Arie forever. But her song might not be. In Australia, Arie is struggling to cope with his loss. In Scotland, a woman named Evie is taking stock of her life after the end of another lackluster almost-relationship. Years of wandering the globe and failing to publish her poetry have taken their toll, and she finally might be ready to find what her travels have never been able to give her: a real home. And through a quirk of fate or circumstance, Diana’s song is passed from musician to musician. By winding its way around the world, it just might bring these two lost souls together.
