Florence Fairfax isn’t lonely. She loves her job at the little bookshop in Chelsea and her beloved cat Marmalade keeps her company at night. She might have been single for quite a while – well, forever actually, if anyone’s asking – but she’s perfectly happy, thank you. And then Florence meets eccentric love coach Gwendolyn, and everything changes. 

When Lee first came to Amsterdam, it was with a newborn baby and a secret. Five years later, her life is approaching normal: her career as a celebrity photographer is flourishing, her son, Jasper, is growing up, and they are enjoying the run-up to Christmas with their tight circle of close friends. But all this changes one morning when Lee finds a book in the basket of her bicycle - and scrawled inside it, a desperate message. Who left it for her, and why? Lee feels compelled to help and tracks down the book’s author, Sam.

After eight years together, Lil Bailey thought she’d already found ‘the one’ - that is, until he dumped her for a blonde 20-something colleague. So she does what any self-respecting singleton would do: swipes right, puts on her best bra and finds herself on a first date with a handsome mountaineer called Max. What’s the worst that can happen? Well it’s pretty bad actually. First Max ghosts her and then, after weeing on a stick (but mostly her hands), a few weeks later Lil discovers she’s pregnant.

He was perfect. Denim blue eyes, a dazzling smile. And he hadn’t sent me a picture of his junk. Which is about as rare, these days, as a dodo. When Sloane met Myles, everything fell into place. He loved a martini almost as much as she did, shared her passion for four-cheese pizzas, and made her laugh harder than any episode of Friends. She’d found 'The One' at last, and she could finally delete Tinder, forgetting all those waste-of-space men she’d never have to date again. But then she finds out that Myles has a secret. A very big one.
