Finalist, Governor General’s Literary Award – Young People’s Literature – Text, 2019
“Treggiari. . . offers chills both subtle and shocking, and readers won’t be able to turn the pages fast enough.” —Kirkus Reviews
“A worthy addition to any classroom, school, or home library, is a well-developed psychological thriller filled with unexpected plot twists that will leave readers guessing right until the very end. . . . Highly recommended.” —CM Magazine
“Dark and gripping. . . . [R]eaders will have a hard time putting the book down.” –School Library Journal
“Treggiari’s writing is excellent in the execution of this psychological thriller. The Grey Sisters is definitely perfect to elicit readers to think and wonder about many things: life, relationships, hope, family, but most of all survival and consequences.” — Resource Links
“There’s a punk sensibility on offer here, a raw look at our society’s underside. She keeps the pace of the Governor General’s Award–nominated book brisk, with raging bears and shootouts, but she has also given the human sisters who go on this pilgrimage distinct — and nuanced — approaches to the grief they’re trying to weather.” –Globe and Mail
“I’d recommend The Grey Sisters to anyone who enjoys thrillers, strong female characters, and true crime” –Midwest Book Review
