Orlagh grew up on the northside of Dublin. After studying Communications at Dublin City University she moved to London and entered the film industry there, working on productions such as Calendar Girls and Ali G before taking over as Head of Physical Production at Pathé Films, where she oversaw Breakfast on Pluto and The Queen amongst others. Orlagh co-produced the BIFA-winning documentary Joe Strummer: The Future is Unwritten and the feature film Mary Shelley, starring Elle Fanning.

All The Invisible Things is her second YA novel. She is currently developing the screenplay of her first novel No Filter with Screen Ireland and writing an original coming-of-age screenplay, entitled Lucky Irish.

Orlagh lives in Somerset with her husband and their two children. Loves strong coffee, watching 80’S teen movies and reading pretty much anything involving authentic human relationships. Swears like a sailor.
