When Keira Aiken wrote the book and created the music for Bully - A New Musical, she was only 14 years old.
With Keira being hailed as a "major new talent" by the author whose book the musical is based, the County Antrim teen's work, a contemporary musical in the vein of mega-smash Hamilton, is now set to hit the stage.
The 15-year-old schoolgirl claimed she discovered the book, Bully by Yvonne Coppard, in a box in her attic.
Inspiration then started to flow.
For a very long time, she said, she had wanted to write a musical, but she had no idea on what to base it.
"I believed it might be simpler if I already had a story to work from, and I believed the novel would be a really great place to start.
The themes, in my opinion, would appeal to young people. ".
In order to get permission to transform the book into a contemporary musical, Keira, who is preparing for her GCSEs, contacted the author.
She "immediately impressed me with her ideas, her dedication, and her confidence," according to Ms. Coppard.
Even for a seasoned composer/director, bringing a book to the stage as a musical requires a significant creative leap, according to the speaker.
"I am beyond happy that Keira has pulled it off, and I wish the production nothing but success.
"I believe the audience will be watching the emergence of a significant new talent. ".
The musical is currently in rehearsal for its performance at the McNeill Theatre in Larne on February 25. All ticket sales will benefit the NSPCC.
It was the first time a teen had written a script and composed the music for one of Ryan Moffett's productions, according to Uplift Performing Arts' Ryan Moffett.
It was a fantastic accomplishment for a then-14-year-old, said Ryan, who was very impressed when he first received the script.
It appears to have been somewhat influenced by current musicals like Hamilton and In the Heights.
A contemporary rap musical based on the book has been created, and it has a very significant message for young people. ".
Keira has been involved at every stage, from auditions to direction, even though she is not one of the 16 members of the cast.
According to Michael Aiken, her father, who spoke to BBC News NI, he did not anticipate it going on stage.
She plays a variety of instruments and has always composed music, he continued.
"We assumed that this was just another immature teen's failed project.
"However, the fact that it has legs and will appear here in a few weeks is daunting, but we're ridiculously proud.
