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. Catherine 'Cat' Willows is the new girl in school, and her odd behaviour is attracting the wrong kind of attention. Stacey feels sorry for her, and takes Cat under her wing, trying to be a friend. Things seem fine until the new girl begins to follow her everywhere, starts dressing exactly like her and tries to drive a wedge between Stacey and everyone she cares about. Just where will this unhealthy obsession end?
