This inventive adventure presents a unique world where ghosts bond with water to become clouds, lose themselves in rivers, and read your thoughts through rain. It's a satisfying and often surprising fantasy world that children will no doubt enjoy coming back to again and again. * Booktrust, Great Books Guide 2022 * One of 'Waterstones best children's books of 2021' * Waterstones * 'Fantasy fans will dive headlong into this imaginative, action-packed debut' * The Guardian * Smartly wrought worldbuilding aptly engages with themes of identity and equity while conjuring an atmospherically gritty London that's at once singularly inventive and reminiscent of works by Joan Aiken, Charles Dickens, and Philip Pullman. It's a thoughtful and well-built fantasy that's also rollicking good fun * Publishers Weekly, Starred Review * Charles Dickens, Philip Pullman's His Dark Materials, and Neil Gaiman's The Graveyard Book rolled into one. Mann creates empathy for Luke, who shows clear hope and compassion for others during this evil time. The quick-witted humor and fast pace keep the entertainment factor high. Thrilling. * Kirkus Reviews, Starred Review * This inventive adventure presents a unique world where ghosts bond with water to become clouds, lose themselves in rivers, and read your thoughts through rain.
