Charlotte Grimshaw is the New Zealand author of seven critically acclaimed novels, Provocation, Guilt, Foreign City, The Night Book, Soon, Starlight Peninsula and Mazarine, two short story collections, Opportunity and Singularity, and a memoir, The Mirror Book.

She is a winner of the BNZ Katherine Mansfield Award. Her story collection Opportunity was shortlisted for the prestigious Frank O’Connor International Prize, and won New Zealand’s premier Montana Award for Fiction, along with the Montana Medal for Book of the Year. She was also the Montana Book Reviewer of the Year. Her story collection Singularity was shortlisted for the Frank O’Connor International Prize and the Asia Pacific Commonwealth Writers’ Prize. Her novel, The Night Book, was a finalist for the New Zealand Post Award. Grimshaw’s fifth novel, Soon, a bestseller in New Zealand, was published by Jonathan Cape in the UK and by Anansi in Canada and the United States. These two novels were made into a TV series, The Bad Seed, which screened on TV One in 2019. Her novel Mazarine was longlisted for the 2019 Ockham Book Awards.

In 2021 she published her bestselling memoir The Mirror Book, which was shortlisted for the Ockhams New Zealand Book Awards. The judge's report states 'The prose in Charlotte Grimshaw's The Mirror Book is exquisitely precise in its navigation of the complexity of the author's family dynamics.'

In a review for the Academy of New Zealand Literature, Rachael King writes 'The Mirror Book is a fascinating portrait of not only a family, but the writing process. How we magpie material (go and make a story out of it) and what we build from it — and at whose expense? And where the line between fact and fiction is drawn... The writing in this memoir is astounding.'
