Silver — Chris Wooding

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.
