Perfect for pupils with a low reading age of 8 to 9, but a high interest age of 12 to 15, our Teen Reads will have readers on the edge of their seats. Just the right level of challenging vocabulary and plot-lines make these books highly accessible, drawing readers into exciting worlds whilst simultaneously developing their reading skills. A normal school day is the beginning of a desperate mission for Hildy and her friends, Luca and Ryan, when a mysterious package is left in Hildy's bag. The package contains a strange object, a map reference and a message with a single, pleading word: URGENT!
