"A stunning, achingly beautiful and gripping mystery. Full of page-turning suspense, intrigue, and secrets, The Undercurrent is also a heartfelt story of family, childhood, and the nature of obsession. I loved it.” —Chris Whitaker, author of All the Colors of the Dark
“Brilliant…I read The Undercurrent like I was under a spell, accompanied only by my own goosebumps. It’s a book about being a mother—in all the dull, punishing, and stunning ways—but then there’s also a...chilling mystery at its core. Pure glinty, flinty, propulsive perfection."—Catherine Newman, author of We All Want Impossible Things
“With The Undercurrent, Sarah Sawyer puts a spell on her reader. The story is immersive and taut, with an increasing sense of unease that kept me turning the pages. I wanted to know what happened next because of the mystery at the center of the book but also because I came to care deeply for these characters—a testament to Sawyer’s lyrical and tender depiction of them. I read the last chapters with my heart in my throat. Readers of Tana French will love this literary page turner.” —Kate Hope Day, author of In the Quick
"Sarah Sawyer takes us on a gorgeous, twisting voyage through a shadowed landscape of memory and mystery. The Undercurrent truly carried me away. This is a shimmering debut."—Debra Jo Immergut, author of You Again
