Jacqueline Wilson on the easiest and hardest book Ive ever written

Jacqueline Wilson has been writing for more than five decades and has published hundreds of books. She describes her new novel Picture Imperfect - her adult sequel to the The Illustrated Mum - as "the easiest and the hardest thing" shes ever written.

Published in 1999, The Illustrated Mum tells the story of two sisters - Dolphin and Star - who struggle to cope with their unstable and heavily tattooed mother Marigold, whose bipolar disorder threatens to pull their family apart.

The sequel focuses on Dolphin, 33, still looking after her mum and feeling dejected with life living in a bedsit and working at a tattoo parlour.

"It was easy because I loved that book," Wilson tells me over a cup of coffee in a room at the Penguin Random House office, piled high with her books.

"But it was hard because people carry their own ideas of what might have happened to those characters.

"Some wanted Marigold to have recovered, or Dolphin to have a wonderful career, or Star to be the perfect big sister but real life doesnt always work that way and Ive always wanted my books to be true to life."

Truth, even when uncomfortable, has always been Wilsons trademark. From Tracy Beaker to Dustbin Baby to The Illustrated Mum, she has written about messy families, mental illness, poverty and the resilience of children navigating it all.

The much-loved author, who was made a dame in 2008, admits she has long felt a particular affection for The Illustrated Mum and it "is one of my favourite books".

"Its upsetting in some ways, but I had so many letters from children saying, thats just like my mum or my dad," she says.

"Recently at a concert, a woman hugged me and said thank you for helping me deal with my mum and it almost made me cry. To think a book could matter like that all these years later, thats why I wanted to revisit them."

The three womens lives have unfolded in ways both expected and painfully believable - Marigold is still not managing to take her medication or settle into stability. Star has qualified as a doctor and lives in Edinburgh, detached from Marigolds mental health problems.

And then there is Dolphin, who Wilson sympathises with most as "shes always the go-to person, the one holding things together when Marigold gets into bizarre scrapes".

"Shes caring but resentful, struggling with relationships and not fulfilled," she explains. "In this book, I wanted to give her choices in love and in work so she could figure out what she really wants."

When The Illustrated Mum was first published, Wilson was warned that a particular scene - where Marigold covers herself in toxic white paint to hide her tattoos - might be "too stark" for children.

"I was told it was scary, maybe too much," Wilson recalls. "But I thought, no, that moment was what would push Dolphin to finally get help. It had to be there and luckily, I got my way."

Wilson insists she has no regrets about the tougher themes in her books, despite occasional criticism that she was going too far.

What makes her laugh, though, is remembering a complaint from a furious mum who accused her of ruining her daughters childhood because one of her books implied that 11-year-olds no longer believe in Father Christmas.

"You cant please everyone," Wilson chuckles.

Yet, for all her boundary-pushing, she is clear about where she draws the line.

She acknowledges young people now are exposed to far more than readers were in the 1990s or 2000s, with conversations about misogyny, online abuse and even incel culture filtering down into classrooms.

But she says those darker realities belong in her adult fiction rather than her childrens books.

"If I were to put something as troubling as the whole incel thing into a childrens book, it would only ever be implied," she explains. "With adult books, you can more or less write what you want. With children, you have to balance being honest without overwhelming them."

Wilsons commitment to honesty - sometimes shocking, but never gratuitous - remains intact in Picture Imperfect.

"Its not a self-help book," she says. "Im not saying if youre Dolphin, this is what you should do, but I wanted to show the reality of being the child of a parent with mental illness.

"Often one sibling ends up carrying the burden - sometimes you feel its your duty, sometimes you feel bitterly resentful. There are no easy answers."

The author knows a thing or two about lifes imperfections herself. Having married young, she speaks frankly about the mismatch with her ex-husband and the lonely years that followed.

"I remember a day when my marriage had just broken up, my boiler nearly caught fire, I had no food in the fridge and I was up at dawn to do four school visits. A teacher said to me that she envied my glamorous life and I thought: If only you knew."

For the past 23 years, the 79-year-old has been happily partnered with a woman, and last year she told me she was "delighted" to be viewed as a gay icon.

One of the most touching themes in Picture Imperfect is Dolphins attempt to understand love. Wilson says she used to be cynical about what love felt like, but that changed when she met her now partner.

"I thought the overwhelming feeling of love was a myth but when I was first dating my partner I really did get butterflies and it was just astonishing."

Given that tattoos are central to both Marigolds flamboyant character and Dolphins chosen career, I ask Wilson if she would ever get inked herself?

She chuckles. "I thought maybe a tiny dolphin would be a nice way of advertising the book but my skins too fragile so maybe Ill just get a henna one."

Last year, Wilson released her first adult novel, Think Again, a sequel to the Girls series. It became the bestselling adult debut hardback of 2024.

She tells me she relishes the freedom of adult fiction. "In childrens books, you cant go too far - you dont want to frighten or bore kids with adult details. With adult books, you can put in whatever feels true so its like getting two bites of the cherry and I feel very lucky."

So will more beloved characters reappear in her adult novels? Wilson is coy, but hints she is already 30,000 words into another sequel.

I spend the next ten minutes guessing which character will be the protagonist of the new novel but Wilson only laughs along, giving nothing away.

She appeases me by telling me I will be the first person to know when its finished.
