Fourteen-year-old Shan Shan has always been gifted (or plagued) with the ability to see and hear things that either supposedly don't exist or shouldn't talk. One day, he is attacked by a karmavore—a monster created from other people's evil deeds! Narrowly escaping death thanks to a Guardian, Shan Shan is offered the chance to become a Guardian himself. But being a Guardian sounds like too much work. And although Shan Shan (reluctantly) agrees, he's not very good. With fellow classmates Cassie and Adam, hopefully he'll be able to make it through all the ordeals of becoming a hero, saving the world and being a teenager. So begins, The Adventures of Shan Shan.
