She remembers wondering how hard it could be to write a Mills & Boon romance as the idea of becoming an author took hold. "Quite hard, as it turned out."
Even so, her first manuscript was picked up by a bricks-and-mortar publisher and almost unheard of, she got a two-book deal.
Each year Evans publishes three to five books of varying lengths, admitting she's a slow writer – some authors crank out eight titles a year.
"Romance readers are ferocious readers so not only do you need to be able to tell a good story, but you need to be aware of how the romance market works. Building up a backlist as quickly as you can is critical to financial success. Readers aren't buying books to put on their shelves, they want 'done and the next one', escapism and fun."
And sex. The catch-all "romance" might conjure up images of an elderly Barbara Cartland lounging on a pink sofa in a pink gown but this massive market has spawned a plethora of sub-genres with Regency romances, already one of the most popular, boosted even further thanks to the Netflix series Bridgerton, which was based on books by American writer Julia Quinn.
"There's a whole lot of reasons why some books do well," says Bronwen, "and it can just be a lucky break like a producer without anything to read finding your book in a holiday rental.
"There's a second Bridgerton series out at the end of the year and that's when we'll see readers moving on to other authors."
Uncoincidentally, Evans, who writes several Regency romance series, will have a new book out at the same time Bridgerton screens. She also writes historical romances set in other periods and has a couple of contemporary romance series too.
"I write sensual romance, not erotica," she says, "and yes some of the characters will have sex, but only if it's important to the story.
"Romance is a genre about women written mainly by women so it's more modern and focused than it's ever been – women are writing what they want to read. Traditional publishers are no longer the gatekeepers of what gets into print."
