When David's uncle comes to visit he sets off a bizarre series of events. Things become complicated when the pet rats turn bright red. David senses that somehow the red rats are connected to the story he is reading, and he becomes more convinced when the colour red becomes contagious. The parallel story sees Felix and his friend Bella inadvertently shifted into a strange land where they must solve a riddle. But this puts them into great danger. How will they escape and find their way home? Young readers will want to solve the confusing conundrum of the red rats; they'll delight in the word riddles and be absorbed by David's story as well as by the fantastical adventures of Felix and Bella, skilfully told by the NZ Post Award-winning writer James Norcliffe.
