In BLOOD SUCKERS, the characters from the first four books of the HIGH SCHOOL MURDER series are united at USC to solve the mystery of who is sucking the blood out of pets and campus coeds. Hamish Garza moves into the Zoo and finds himself the newest inmate of a house of kids with bloody pasts. Hamish is the "normal guy" -never killed anyone, nor has anyone tried to kill him, but all that changes. He finds out that living at the Zoo can be hazardous to one's health. There is a film to make and everyone pitches in. The Zoo takes to the hills outside Los Angeles to shoot raw footage until the homicidal madman shows up to create the kind of havoc that forces the young veterans into action to save the life of one of their own.
