"Marlow’s steady, nurturing presence is balanced by Zach’s heightened sensitivity to his environment, and their bond becomes a central aspect of the novel, which skillfully addresses themes of adaptability, friendship, and the power of family, all while engagingly ratcheting up narrative tension. The emergent fantasy elements feel organic to the story, and the setting of Sun Valley, with its vast forests, is vividly rendered. Throughout, Eatons delicately balances lighthearted moments, such as Zach’s humorous attempts to befriend the town’s uncurious cats, with the feeling of an unseen threat. The plot moves at a brisk pace, with each chapter offering new revelations about the mystery in the woods and strange happenings in the town. Animal characters’ points of view provide intriguing glimpses into deeper forces at play. The story’s climax ties together various narrative threads in a satisfying, imaginative way, leaving room for more adventures." -- Kirkus Reviews
