Having escaped from the half-bombed, blackened power station where he was being imprisoned, 12-year-old Luke is finally reunited with his family above ground. But though Luke tries to readjust, he can't shake the guilt he feels for his friend Ravi, who was left behind, nor the feeling that someone - or something - is watching him from the shadows. With the help of ghost-girl named Alma and his friend Jess, Luke must journey across the country and sea to find Ravi, the friend who was there for him in his darkest hours. And in doing so, he must face his past and confront his deepest fears... A riveting, magical adventure set in the waterways of a richly reimagined England, and the epic conclusion of the Ghostcloud duology. (P)2023 Hodder & Stoughton Limited
