Erk! Aries's best friend is killed in a road crash, but her other friends are stalked and killed by passers-by. She only escapes with the help of a mysterious stranger. Michael sees road rage spiral out of control and bodies in the street. Mason is murderously attacked with a baseball bat by a man he's never seen before. And Clementine is hunted through her small hometown by people she has known all her life. The world has changed forever. Swathes of people - we'll come to call them Baggers - are possessed by a violent rage that they cannot control and the few that aren't must fight for their lives...
For fans of a narrative driven by action, we'd recommend [[Gone by Michael Grant]] in which teenagers are imprisoned by the mysterious Fayz, and [[The Enemy by Charlie Higson]], a zombie schlock-fest.
