When I got pregnant, Will and I didn’t have a clue what we were signing up for. It turns out that there’s loads we weren’t warned about. But even if I feel like I’m waiting for my motherhood powers to come in the post, at least I’ve got Will. Our old life - festivals, sambuca shots, an actual sex life - might be a distant memory, but we can get through anything together, can’t we? At least that’s what I thought until, one day, Will walked out on us.... If I’m on my own (apart from Siri, obviously) can I do this whole parenting thing?

After Josie got dumped by her ex through a note on the fridge, she hasn’t let herself get close to anyone. But when she meets Cameron at a Halloween party, who turns up in the same Ghostbusters costume as her, it’s virtually impossible to stay away. Cameron, a curly haired video-games designer with dazzling blue eyes, the sexiest dimples and the same encyclopedic knowledge of movies as Josie, seems too good to be true. And maybe he is.... Because there’s one teeny tiny problem as Josie falls madly in love.

When Grace’s husband passed away, there was no guidebook for the 27-year-old widow. Crippled with heartbreak, she was also clueless. Was she allowed to wear denim? Should she be shrouded in a black veil? What about T-shirts printed with Tom’s face? Three years later, things look a little different for Grace. She’s adopted two precious girls, and she’s learned some life lessons.

I thought I was sorted on the life front. I was a heart surgeon with a loving partner and two gorgeous little girls. Except my husband’s version of "loving" is lying, cheating, and sleeping his way around London. Which means I definitely deserve a refund. Unfortunately, moving on isn’t that simple. Just because I know how to operate on a heart doesn’t mean I know how to fix my broken one. Plus, I lost the receipt for him years ago, so I’m definitely getting shortchanged. But now that I’m single, am I ready to mingle?

I’m Lucy. Out-of-work actress, part-time princess impersonator, Dorito enthusiast. Oh, and I’ve lost my memory. I got knocked off a bicycle on my way to a children’s party, dressed as Elsa, and accidentally flashed my thong. Now, in my head, it’s 2009 and I’m 17 years old. Not nearly 30 and starting to wrinkle. By this stage of my life, I thought I’d be married, with kids and a mortgage. Instead, I’ve got a phone full of dick pics. As I make my way through my contacts list - and try to jog my memory - I can’t help asking: Am I allergic to love? Commitment? Men?

Meet Nell. Her life is a mess. When her business goes bust and her fiancé with it, Nell's happy ever after in California falls apart and she moves back to London to start over. But a lot has changed since she’s been gone. All her single friends are now married with children, a sky-high real estate market forces her to rent a room in a stranger’s house, and everyone has seemingly perfect Instagram-ready lives. Starting from scratch she feels like a f**k up . . . a forty-something f**k up.

Olivia can’t believe it when her boyfriend, Teddy, proposes out of the blue. She loves him (of course she does!) BUT it does seem sudden, especially when they don’t even live together yet. There is only one place that Olivia has ever wanted to get married - a gorgeous venue on the Cornish coast, built by her grandfather. The problem is they only have one date available - and it's only a few weeks away! Olivia isn't so sure about rushing but Teddy jumps at the chance to be married within the month. Thrown into a whirlwind of wedding planning, alarm bells start to ring for Olivia.

Molly and Andrew are just trying to get home to Ireland for the holidays when a freak snowstorm grounds their flight. As the snow falls over the city and over the heads of two friends who are sure they’re not meant to be together, the universe might just have a plan of its own.

Moving home in her 30s was not the life plan Jas had in mind. So when her best friend gets in touch to say she's arranging a long overdue reunion with their high school friends, Jas is very much up for the escape. Oh, and it's all expenses paid to Italy - so that's a bonus! But while being whisked away to the beautiful Italian coast may seem idyllic, Jas has to come face to face with not only her ex-boyfriend, but the one that got away too!

Cara and Millsy have broken up...sort of. After years of being everyone's favourite couple, always up for a party and having fun wherever they go, things have fizzled out. But when they realise they have a whole calendar of events and celebrations with friends and family coming up, Cara and Millsy can't face letting them down. So they decide to make a pact: just convince everyone they're as madly in love as ever and get through the festivities without causing suspicion, and then deal with the break up in the new year. How hard can it be...?

When Serena is kicked out of her flat, an offer from her friend, Taylor, to house sit for her while she and her husband go travelling could not be better timing. But unfortunately for Serena she’s not the only one to have received this offer. Enter Ziggy: arrogant, messy musician, and friend of Taylor’s husband. Living with him is far from ideal, especially when he claims the best room, has loud parties - and the least said about his kitchen manner the better. There's just one solution for Serena – drive him out of the house by being twice as difficult to live with than he is!

Frankie doesn't believe in true love. As relationships expert at popular magazine Stylife, she has learnt that dating disasters are far more common than happy-ever-afters. So when she is tasked to find out if meet cutes can work in real life, she is up for the challenge—but whether it's being a damsel in distress with a flat tyre or spilling coffee over a stranger, she isn't convinced this can really lead to love. But little does Frankie know that the ultimate meet-cute opportunity is just around the corner.

When Georgie discovers that her fiancé has been cheating on her, only a few days before her cousin’s wedding, her whole world explodes. Facing a romantic trip to Vegas alone, she decides to go out and have some fun…but Georgie never expected to wake up wed! And even worse, she can’t remember who to. So when gorgeous Jack reveals himself as her husband, she can’t believe her luck – he’ll act as the perfect wedding date!

Peach is excited to hear that her sister, Di, is getting married. Of course, she would have preferred her little sister to be engaged to someone she's known longer than a week - and the fact that his name is Charles doesn't bode well - but who is she to judge? After all, her own love life is non-existent, and who doesn't love a destination wedding?

Billie is looking forward to a quiet, man-free Christmas. It’s just a shame her family doesn't feel the same way. With a house full of unexpected (and unwanted) guests, Billie needs to find the perfect escape to get away from the chaos. So when her dating app recommends a week of singles nights in her area, Billie decides that braving these events has to be better than making conversation with her dad’s new wife, dealing with her mum's mid-life crisis or witnessing her sister flirting with her insufferably arrogant next-door neighbour.
