Meet Emma Corrigan, a young woman with a huge heart, an irrepressible spirit, and a few little secrets.

Poppy Wyatt has never felt luckier. She is about to marry her ideal man, Magnus Tavish, but in one afternoon her “happily ever after” begins to fall apart. Not only has she lost her engagement ring in a hotel fire drill but in the panic that follows, her phone is stolen. As she paces shakily around the lobby, she spots an abandoned phone in a trash can. Finders keepers! Now she can leave a number for the hotel to contact her when they find her ring. Perfect!

Fixie Farr has always lived by her father’s motto: “Family first.” And since her dad passed away, leaving his charming housewares store in the hands of his wife and children, Fixie spends all her time picking up the slack from her siblings instead of striking out on her own. The way Fixie sees it, if she doesn’t take care of her father’s legacy, who will?

Everywhere Katie Brenner looks, someone else is living the life she longs for, particularly her boss, Demeter Farlowe. Demeter is brilliant and creative, lives with her perfect family in a posh townhouse, and wears the coolest clothes. Katie’s life, meanwhile, is a daily struggle—from her dismal rental to her oddball flatmates to the tense office politics she’s trying to negotiate. No wonder Katie takes refuge in not-quite-true Instagram posts, especially as she's desperate to make her dad proud.

When the spirit of Lara’s great-aunt Sadie–a feisty, demanding girl with firm ideas about fashion, love, and the right way to dance–mysteriously appears, she has one last request: Lara must find a missing necklace that had been in Sadie’s possession for more than seventy-five years, and Sadie cannot rest without it. Lara, on the other hand, has a number of ongoing distractions. Her best friend and business partner has run off to Goa, her start-up company is floundering, and she’s just been dumped by the “perfect” man.

When 28-year-old Lexi Smart wakes up in a London hospital, she's in for a big surprise: Her teeth are perfect. Her body is toned. Her handbag is Vuitton. Having survived a car accident - in a Mercedes no less - Lexi has lost a big chunk of her memory, three years to be exact, and she's about to find out just how much things have changed.

Sasha has had it. She cannot bring herself to respond to another inane, “urgent” email or participate in the corporate employee joyfulness program. She hasn’t seen her friends in months. Sex? Seems like a lot of effort. Even cooking dinner takes far too much planning. Sasha has hit a wall. Armed with good intentions to drink kale smoothies, try yoga, and find peace, she heads to the seaside resort she loved as a child. But it’s the off season, the hotel is in a dilapidated shambles, and she has to share the beach with the only other occupant: a grumpy guy named Finn.

Ava thinks love should be found in the real world, not on apps that filter men by height, job, or astrological sign. She believes in feelings, not algorithms. So after a recent breakup and dating app debacle, she decides to put love on hold and escapes to a remote writers' retreat in coastal Italy. At the retreat, she's not allowed to use her real name or reveal any personal information. When the neighboring martial arts retreat is canceled and a few of its attendees join their small writing community, Ava, now going by "Aria", meets "Dutch", a man who seems too good to be true.

For Rebecca Bloomwood, life is peachy. She has a job on morning TV, her bank manager is actually being nice to her, and when it comes to spending money, her new motto is Buy Only What You Need—and she's really (sort of) sticking to it. The icing on the brioche is that she's been offered a chance to work in New York.

After being together for 10 years, Sylvie and Dan have all the trimmings of a happy life and marriage; they have a comfortable home, fulfilling jobs, and beautiful twin girls and communicate so seamlessly, they finish each other's sentences.

In the name of marriage survival, they quickly concoct a plan to keep their relationship fresh and exciting.
