19 Books with Margaret Atwood

Heather Sangster of Strong Finish has worked with internationally best-selling and award-winning author Margaret Atwood on 19 consecutive titles and counting.

Starting in 1995 with  the poetry collection Morning in the Burned House, Heather has copy edited and proofread not only Atwood’s poetry but also her non-fiction and fiction, including The Testaments, the 2019 Booker Prize–winning sequel to The Handmaid’s Tale.

Margaret Atwood is the recipient of multiple prestigious awards, including the Commonwealth Writers’ Prize, Giller Prize, and the National Book Critics and PEN Center USA Lifetime Achievement Awards. A number of her books have been adapted for film, television, and theatre.

“Many thanks are due to … Heather Sangster of Strong Finish, the demon copy editor who picks every nit, including those yet unhatched.”
~ Acknowledgements in The Testaments

“Heather Sangster has been the primary copy editor of my work for the past 28 years and my publications owe a great deal to her services. She is meticulously thorough and thoroughly professional.”
~ Margaret Atwood
