Plague House

Charlie Wainwright is a sickly child, whose life has been rigidly controlled due to his illness, a rare auto-immune disease. His protective parents don't allow him to do anything normal children get to do. He can’t partake in sports. He can’t have friends or visitors at home. He must avoid anything that can cause him to have a flare-up of his condition.The only place his parents let him go is school, where Charlie is one of the Sicko Squad, a group of chronically sick kids often bullied by other students.

After Charlie starts high school, his illness worsens, and he discovers the true nature of his illness-- not the auto-immune condition his parents led him to believe he had, but something much more startling.

Charlie is becoming a vampire.
