SHE is a teenager who became a global sensation by writing a series of best-selling books.

Now, after going down a storm on recent trips to France and the United States, 19-year-old Estelle Maskame has confirmed she will unveil a new book next July.

The author, from Peterhead, Aberdeenshire started her “DIMILY” series when she was 15 and gained a publishing deal with Scottish company, Black & White, at the end of 2014.

Since then, following the publication of the trilogy, “Did I Mention I Love You”, “Did I Mention I Need You” and “Did I Mention I Miss You”, Ms Maskame has become one of the biggest names in Young Adult fiction, gained a worldwide legion of fans, and more than 150,000 Twitter followers.

Estelle is just 19 and attended Peterhead Academy and still speaks in a rich Doric accent.

She was encouraged to write by her English teacher and created a series on Wattpad about the turbulent lives of Eden and Tyler, two teenagers based in Los Angeles.

The online editions turned into a global phenomenon and they were read by four million people across the world.

Until last year, she worked at weekends in Asda.

So far, there have been few details released about her new book, but it is understood it is a romance and Campbell Brown, the managing director of Black and White, said yesterday: “Estelle’s story is already phenomenal, with so much more to come. She’s had the drive to write a trilogy in her teens, and the talent to engage hundreds of thousands of YA readers throughout the world.

“Estelle is already an international best-selling author and her eagerly awaited new novel, which is due to be published in July, 2017, is set to build on her incredible success.”

Ms Maskame was in Paris last week, where long queues of fans waited patiently to buy copies of works which have already been translated into a dozen languages.

And although she has travelled a long way since she used to work at the supermarket in Peterhead, she has taken it all in her stride, even as there have been discussions about turning her books into a film or TV series.

Ms Maskame, who has just returned home said yesterday: “It’s been an amazing experience getting to travel around Europe to meet my readers in other countries.

“I’m currently writing a new standalone Young Adult novel and I can’t wait to introduce my readers to a new set of characters. This is what I’ve always wanted to do, and it’s fantastic to be moving forward.”
