Claire has everything she ever wanted: a husband she adores, a great apartment, a good job. Then, on the day she gives birth to their first baby, James informs her that he's leaving her. Claire is left with a newborn daughter, a broken heart, and a postpartum body that she can hardly bear to look at. She decides to go home to Dublin. And there, sheltered by the love of a quirky family, she gets better. So much so, in fact, that when James slithers back into her life, he's in for a bit of a surprise.

Meet Rachel Walsh. She has a pair of size 8 feet and such a fondness for recreational drugs that her family has forked out the cash for a spell in Cloisters – Dublin’s answer to the Betty Ford Clinic. She’s only agreed to her incarceration because she’s heard that rehab is wall-to-wall jacuzzis, gymnasiums and rock stars going tepid turkey – and it’s about time she had a holiday. But what Rachel doesn’t count on are the toe-curling embarrassments heaped on her by family and group therapy, the dearth of sex, drugs and rock’n’roll – and missing Luke, her ex. What kind of a new start in life is this?

Maggie has always been the white sheep of the Walsh family.Unlike her comically dysfunctional sisters,Rachel(heroine of Rachel's Holiday) and Claire (heroine of Watermelon), she married a decent man who adored her and found herself a solid career. Where Rachel was reckless and Claire dramatic, Maggie settled early for safety. Or so she believed until she discovers that her husband is having an affair and her boss is going to fire her. Suddenly, her perfectly organized life has become a perfect mess. Devastated, she decides the only thing to do is to run for the shelter of her best friend, Emily, who lives in Los Angeles. There, with the help of sunshine and long days at the beach, she will lick her wounds and decide where life will take her next.But from the moment she lands in the City of Angels, things are not quite what she expected. Overnight, she's mixing with movie stars,even pitching film scripts to studios.Most unexpectedly of all,she finds that just because her marriage is over,it doesn't mean her life is. In the end neither the City of Angels nor Maggie Walsh will ever be the same again.

Anna Walsh is officially a wreck. Physically broken and emotionally shattered, she lies on her parents' Dublin sofa with only one thing on her mind: getting back to New York. New York means her best friends, The Most Fabulous Job In The World™ and above all, it means her husband, Aidan. But nothing in Anna's life is that simple anymore... Not only is her return to Manhattan complicated by her physical and emotional scars – but Aidan seems to have vanished. Is it time for Anna to move on? Is it even possible for her to move on? A motley group of misfits, an earth-shattering revelation, two births and one very weird wedding might help Anna find some answers – and change her life forever.

Helen Walsh doesn’t believe in fear – it’s just a thing invented by men to get all the money and good job – and yet she’s sinking. Her work as a Private Investigator has dried up, her flat has been repossessed and now some old demons have resurfaced. Not least in the form of her charming but dodgy ex-boyfriend Jay Parker, who shows up with a missing persons case. Money is tight – so tight Helen’s had to move back in with her elderly parents – and Jay is awash with cash. The missing person is Wayne Diffney, the ‘Wacky One’ from boyband Laddz. He’s vanished from his house in Mercy Close and it’s vital that he’s found – Laddz have a sell-out comeback gig in five days’ time. Things ended messily with Jay. And she’s never going back there. Besides she has a new boyfriend now, the very sexy detective Artie Devlin and it’s all going well, even though his ex-wife isn’t quite ‘ex’ enough and his teenage son hates her. But the reappearance of Jay is stirring up all kinds of stuff she thought she’d left behind. Playing by her own rules, Helen is drawn into a dark and glamorous world, where her worst enemy is her own head and where increasingly the only person she feels connected to is Wayne, a man she’s never even met.

For all fans eagerly awaiting Marian Keyes' new novel The Mystery of Mercy Close - featuring Helen Walsh and out in September - here is a laugh-out-loud ebook-only short guide to everyone's favourite dysfunctional Irish family, Mammy Walsh's A-Z of the Walshes. It does exactly what it says on the tin but here's a brief word from its author, Mammy Walsh herself: 'There's this woman I know from bridge, Mona Hopkins, a lovely woman she is, even if I must admit I'm not that keen on her myself, and she said a great thing the other day. I was expecting her to say "Two no trumps," but instead she comes out with a saying about her children. She says, "Boys wreck your house and girls wreck your head." Isn't that a marvellous bit of wisdom - "Boys wreck your house and girls wreck your head!" And God knows it's the truest thing I've heard in a long time. I should know. I have five girls. Five daughters. And let me tell you, my head is wrecked from them. Although, now that I think of it, so is my house . . .' It's the perfect re-introduction to the Walsh family and Marian's new novel, The Mystery of Mercy Close.

In her twenties, Rachel Walsh was a mess. Since her spell in rehab, though, she's come a long way on the road to recovery - and now, she's ready to go back to where it all began. But this time, the student has become the teacher. She used to hate the staff in charge of treating her addiction. Now, she's one of them. Rachel's finally got herself on track - but life never stops being messy. And when an old flame resurfaces, will she go back to who she once was? Or nearing fifty, can she find herself all over again?

Anna has just lost her taste for the big apple . . . Anna has a life to envy. An apartment in New York. A well-meaning (too well-meaning?) partner. And a high-flying job in beauty PR. Who wouldn't want all that? Anna—it turns out. Turning a minor mid-life crisis into a major life event she packs it in, heads back to Ireland, and gets a PR job for a super-high-end coastal retreat. Tougher than it sounds. Newsflash: the locals hate it. So much so, there have been threats—and violence. Anna, however, worked in the beauty industry. There's no ugliness she hasn't seen. No wrinkle she can't smooth over. Anna's got this. Until she discovers that leaving New York doesn't mean escaping her mistakes. Once upon a time she'd had a best friend. Once upon a time she'd loved a man. Now she has neither. And now she has to face them. We all make mistakes. But when do we stop making the same one over and over again?
