Dublin heartthrob Eoin Macken is already working on his second book, even though he only launched his debut novel - Kingdom of Scars - last week, the Diary can reveal.
"I'm writing another book at the moment," he said. "When you write a book, people legitimise it by actually reading the book and so it's almost okay to write another one. I'm actually putting in the time now to write the next one.
"It's kind of a little bit like Grapes of Wrath, it's about an 18-year-old boy in New Mexico - it's kind of a travelling story.
"It's kind of in the middle of being written so I've no idea where it's going to go but it's a different style," he added.
Even though he's a famous actor, known for roles in BBC's Merlin and NBC's Nightshift, he admits he prefers writing to acting.
"You've more time and you don't have someone over your shoulder saying you have to do this or that and I like it because it's something you create."
The former Fair City actor also has no plans to star in a movie version of his debut novel.
"I'm definitely going to make it into a film, it just depends on when. I can't play the lead character because he's 15," he said.
"I'm not going to be in it though, I'm just going to direct. I would obviously have a hand in casting.
"I'll definitely be shooting it in Ireland. This is part of why I wrote the book, I wanted to make it into a film and make it here in Ireland," he said.
The 31-year-old has also been cast in a new series called Killing Jesus.
Macken was hand-picked for the part of young Herod in the four-part mini-series which also stars Frasier's Kelsey Grammer, Lord of the Rings actor John Rhys Davies, and Rufus Sewell.
The mini-series is being made by Ridley Scott's production company for the National Geographic Channel and is being shot in Morocco.
"It is fantastic fun because I usually play the easy-going drunk dude and this is a proper bad guy, a meaty role and it's harder to portray," he said.
"It's very political and I make grand speeches - I think it might ruffle some feathers," he added.
Nightshift Following filming in Morocco, Macken will be flying back to New Mexico for six months to start filming the second series of the Nightshift.
The medical drama follows staff on the overnight shift at San Antonio Memorial Hospital and Macken plays Dr TC Callahan.
"We shoot the whole series in Albuquerque, New Mexico, it's like Breaking Bad basically. It's shot in the same place," he said. The show has been picked up by RTE and will be broadcast to Irish audiences next year as part of their spring schedule.
"It's coming to RTE in January, I'm actually more nervous about it being on in Ireland. All Irish people will be watching it now," he added.
