Eileen Merriman's first young adult novel, Pieces of You, was published in 2017, and was a finalist in the NZ Book Awards for Children and Young Adults and a Storylines Notable Book. Since then, a stream of novels for adults and young adults have followed. She has received huge critical praise, with one reviewer saying- 'Merriman is an instinctive storyteller with an innate sense of timing.' In addition to being a regular finalist in the NZ Book Awards for Children and Young Adults, Merriman was a finalist in the 2021 Ngaio Marsh Award for Best Crime Novel and Moonlight Sonata was longlisted for the Jann Medlicott Acorn Prize for Fiction 2020. Editions of some of her young adult novels have been released in Germany, Turkey and the UK and three have been optioned for film or TV, including the Black Spiral Trilogy. Her other awards include runner-up in the 2018 Sunday Star-Times Short Story Award and third in the same award for three consecutive years previously. She works as a consultant haematologist at North Shore Hospital.
