The final exam is survival. Paul is the new kid at Mortingham Boarding Academy, and he has a dark secret. Caitlyn admires Paul from afar and resents that he only has eyes for Erika. Erika thinks that she and Caitlyn are best friends, but she's wrong. Adam is a bully with a major chip on his shoulder. Mark is outgrowing his old friends but doesn't know how to make new ones. In a few short hours, none of this will matter. Without warning, a horrifying infection will spread across the school grounds, and a group of students with little in common will find themselves barricaded in a classroom, fighting for their lives. Some will live. Some will die. And then it will get even worse. Fast-paced and frightening, Silver is a tale set on the fringes of science and horror, a story about the struggle to survive in the face of impossible odds.
