Louise O'Neill has re-imagined the Little Mermaid through a feminist lens for her latest book, moving the action to the Atlantic Ocean off the Irish coast. The Surface Breaks is her second new book in as many months, following on from her third novel, Almost Love, and comes just a few weeks before the stage adaptation of her award-winning second book, Asking for It, debuts at the Everyman Theatre in Cork. She talks to Roisin Ingle about the joy of seeing her book come to life on stage, the trouble with people confusing her writing for works of non-fiction and why she will never be tempted to publish two books in two months again.
