Irish Novel 'Her Hidden Fire' Optioned for YA Series

Cork-based Great Island has secured the rights to adapt Clíodhna O'Sullivan's bestselling romantasy novel 'Her Hidden Fire' into a young adult series. This adaptation is planned as an eight-part series and will ultimately span three seasons, covering the entire book trilogy. The story centers on Éadha, a servant who must conceal her own powerful magic in a stratified world where magical energy is derived from enslaved individuals known as 'Fodder.'

Éadha's hidden power becomes a significant element when she secretly uses it to aid Ionáin, the last heir to his family and the boy she loves. This act binds her to an academy built upon exploitation, forcing her to uncover the truth about the system. As she delves deeper, her burgeoning power poses a threat not only to the exploitative system but to everyone within it.

'Her Hidden Fire,' O'Sullivan's debut novel, has achieved considerable success, including being named an Amazon Editors' Best Book of 2026 and a Good Morning America literary pick, alongside becoming a USA Today and UK bestseller. The second installment is scheduled for publication in November 2026, with the third to follow in July 2027. Great Island, known for developing Irish stories with international appeal, aims to develop the 'Hidden Fire' franchise with creative and production partners.
