"Cornwell's themes of body image, abuse, and the danger and pleasure found in relationships of all kinds emerge organically through the book's visceral, disturbing, and often lovely imagery." -- Publishers Weekly, starred review "[A] graceful debut novel. The narrative shimmers and haunts, and will appeal to readers who don't typically like fantasy." -- Booklist "Cornwell seamlessly weaves together three distinctive narrative voices to tell a completely original story. [Tides] offers a valuable message of acceptance." -- VOYA, 4Q 3P J S "A satisfying mix of folktale, mystery, and family drama, this eerie story will leave readers with the distinct impression that Gemm's island home has a bottomless supply of heartbreaking tales of love and loss." -- The Bulletin of the Center for Children's Books "A haunting, atmospheric, intergenerational tale of the "inbetween," suffused with selkie lore." -- Kirkus "Subtle themes of turning weakness into strength and threaded throughout the story and ultimately create a nuanced debut novel.

An insightful and compelling work." -- School Library Journal "Longing for the beyond vies with the deep bonds of love, home, and family in Betsy Cornwell's dreamlike and heart-wrenching novel, and her fresh, delicate lyricism conveys her characters' struggles with compelling power. A truly beautiful debut!" -- Sarah Porter, author of the Lost Voices trilogy " Tides is a rich, taut, suspenseful, and funny exploration of two worlds, selkie and human.  It's full of mystery but it's also so fully imagined that a reader can jump right in.  Betsy Cornwell is a terrific new talent with a boundless imagination." -- Valerie Sayers, author of Who Do You Love and Brain Fever.
