From drafting her first book at home in her parents' spare room to being flown to New York to discuss her first film deal, it’s certainly been four years of extremes for Cork native Louise O’Neill.
After over a year working for ELLE magazine in the US, O’Neill moved home in September 2011 with a plan – to write her first novel. Just over a year later, she had a full first draft of Only Ever Yours under her belt, which went on to win her the Newcomer Of The Year Award at the Irish Book Awards in 2014.
Pausing during our interview to hug her mum goodbye (“She’s off to Thailand!”) it’s clear O’Neill still has strong roots at home in West Cork. But over the last twelve months her life has spiralled in a million different directions – most notably last September, when US film/TV studio Killer Content bought the rights to Only Ever Yours.
"They flew me first class to New York and threw me a party on a yacht with Eva Longoria. It was all very surreal," she recalls to SHEmazing! from her family home in Clonakilty, where she’s spending the night before travelling back to Dublin for a panel discussion at the Mountains to Sea Book Festival.
"I could never have anticipated it when I first started writing. I was just thinking of the next thousand words."
While that undeniably huge level of success might be enough to keep some young authors going, O’Neill barely stopped for a minute before penning her second – and equally lauded – book, Asking For It, which threw up a whole new set of "firsts" for her.
Chief among those is the fact that she’s become something of an unintentional activist for consent and sexual violence issues in Ireland, largely due to the subject matter of Asking For It.
The story of a Leaving Cert student who has her life ripped apart after explicit images of her end up online has struck a chord with Irish readers, not just in the Young Adult sphere but everywhere else, too.
"Even early on, when I was researching the book, I realised that rape and consent were much bigger issues in Ireland than I had ever known," she recalls.
"Women were coming to me and telling stories, saying things like ‘Oh, I had an unpleasant sexual experience,’ or ‘I was drunk, I said I didn’t want to have sex but we did’… Things that made me think, ‘That sounds like the definition of rape to me.’"
And even now, O’Neill is still asked to advise, help or just to be a listening ear to countless readers.
"I get emails every single day from women sharing their experiences – survivors or people going through things right now that Asking For It has helped them to understand," she says.
"It’s just been this ripple effect from where I first started, at home in my parents' spare room in my PJs, on the laptop.
"It’s humbling and gratifying but it’s also terrifying… The main thing I try to do is to listen and to be there."
Despite the ever-blurring divide between, as she puts it, "artist and activist," O’Neill is still on track with her third book, which she hopes to have finished by early next year.
"I do feel off-kilter at the moment, but I have a blanket ban from June  to January , and that’s when I’ll stay at home and really get into the writing. I need that stability and normality."
While O’Neill says she’s too "superstitious" to discuss the plot of her third novel just yet, she’s already started speaking to women and crafting "the voice of my main character."
For now though, it’s back on the road – first to UCC later in the afternoon for a creative writing workshop, and onward to Dublin tomorrow.
"It never stops," she laughs. "But it’s great. It’s brilliant."
