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 plotlines 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!
