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?

Mabel Beaumont’s husband Arthur loved lists. He’d leave them for her everywhere. ‘Remember: eggs, butter, sugar’. ‘I love you: today, tomorrow, always’. But now Arthur is gone. He died: softly, gently, not making a fuss. But he’s still left her a list. This one has just one item on it though: ‘Find D’. Mabel feels sure she knows what it means. She must track down her best friend Dot, who she hasn’t seen since the fateful day she left more than sixty years ago.

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? 

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.

When Olivia Tennyson - or Ollie to her friends - was 16, she wrote a Dream List of all the things she wanted for her life, including a happy marriage and a family. But at 29, Ollie is single, living at home with her over-protective and manipulative mother and is feeling like her dreams are getting further out of reach. It’s time for a change. It’s time to take matters into her own hands.

When Jessie left home at eighteen, she swore she’d never go back. But when life takes a turn for the complicated, she’s forced to move in with her twin, Isaac, and his two best friends. To her dismay, one of these is Elliot, the boy Jessie once loved, until his life was changed forever by a terrible accident that Jessie still blames herself for.

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.

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?

Rosie Jones has been dumped by every boyfriend she’s ever had - most recently by Dinosaur Dave, live on TV, during the ‘phone-a-friend’ segment of a quiz show. After the footage goes viral Rosie receives a bunch of flowers with a message: I love you, I should have never let you go, I want you back x But who sent them?

Thirty-three-year-old Ruth Henderson and her daughter Maggie have some hard choices to make. Following the tragic death of Maggie’s father, they are left with a mountain of debt and broken hearts. So, despite her vow never to return home after the fall-out from her teenage pregnancy, Ruth can’t see any option other than for the two of them to move back in with her parents.

Meet Helen. She worries the walls are closing in. With her children grown and her selfish husband away again, she's full of regrets at not taking the exciting paths she dreamed about in her youth. So when the chance of a last-minute holiday to Cyprus with her two best friends is offered, she grabs it.

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.

Sid wears her independence like armour. So when she strikes up a rare connection with unlucky-in-love Finn, they are both determined to prove that men and women can just be friends. Marin has the perfect home, attentive husband, two beloved children - and a secret addiction to designer clothes. She knows she has it all, so why can't she stop comparing herself to other women? Bea believes that we all have one love story - and she's had hers. Now her life centres around her son, Luke, and her support group of fierce single women. But there's something that she can't tell anyone.

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.

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.
