THEY'RE only in fifth class, but this group of talented pupils are already published authors.
The girls from the Teresian School in Donnybrook spent eight weeks brainstorming story ideas and writing and illustrating their 140-page mystery novel.
The 29 students each wrote a chapter of the book, which is available to download on Amazon for €3.
Proceeds from the book - The Catas-trophy - go to the Irish Cancer Society and Down Syndrome Ireland.
Teacher Caoimhe Ni Fhaolain (32), who helped put her pupils' work together, told the Herald she was delighted with the outcome.
"I'm so proud of them, it's unbelievable. It's a really good story," she said.
"It's well written and I can see people actually wondering about the mystery and thinking 'Who did it?'
"The girls really wanted to raise money for charities that were close to their hearts.
"They had a girl in their class who had Down Syndrome who left for a different school. And everybody knows somebody who's been affected by cancer," she said.
"A storyline was then devised before everyone was randomly given a chapter to write," she added.
