“Simpson brings both a powerful understanding of human emotion and a solid background in natural science to this resonant and exquisitely constructed eco-thriller.”
—Publishers Weekly, STARRED review

“Stunningly wrought . . . The Thinning moves with the compressed momentum of a thriller toward a spectacular climax.”

“Heart-racing . . . [An] emotive tour de force.”
—Australian Women’s Weekly

“Few novels blend environmental concerns and human drama as elegantly as The Thinning by Inga Simpson. Set in a future shaped by ecological collapse and societal upheaval, the story follows Fin as she navigates a dangerous world where survival depends on trust, resilience, and hope. Simpson’s writing is beautifully atmospheric, creating vivid landscapes that feel both haunting and believable . . . What makes the novel particularly memorable is its balance of suspense and reflection. Thought-provoking without ever feeling heavy-handed, The Thinning is a powerful and immersive read that lingers long after the final page.”
—Tulsa Book Review

“The Thinning is an enthralling dystopian novel about the choices, compromises, and moral stands that people make when facing humanity’s possible end.”
—Foreword Reviews

“The Thinning is a very interesting and thought-provoking novel. Simpson seems to have her finger on the pulse of how we both respect the earth and try to destroy in unequal opportunities. And she created a compelling anti-hero in Fin.”
—BVS Reviews

“A spine-tingling literary thriller that will keep you racing to the end. The Thinning blurs the lines between animal, human, and adaptation, and provides a gripping glimpse of our possible future through a fascinating astrological lens. An emotional tribute to the natural world. Moving. Urgent. Beautifully written.”
—Karen Viggers, author of The Orchardist’s Daughter

“Opened the cover; lost the rest of the day. Incandescent, righteously angry, superbly constructed. I am grateful for the reading experience, and grateful that the book was written and published.”
—Michael Winkler, author of Grimmish

“This is a book I wanted to race through and savor in equal measures. Simpson is a writer of astonishing insight into the ways humans simultaneously destroy and revere the environment, and The Thinning is an urgent, exceptional novel. Her best yet.”
—Eleanor Limprecht, author of The Coast

“Grapples with ecological turmoil and grief [with] heart and humanity . . . Simpson’s respect and knowledge of country and astronomy shine through in the evocative language, drawing an exquisite image in the reader’s mind . . . An epic and hopeful journey, perfect for readers of thrillers and novels such as Robbie Arnott’s Limberlost.”
—Books+Publishing
