When Cassie's younger sister Becca winds up in a coma due to a car accident, her cushy world of dances and Friday night football games suddenly becomes a distant memory. Cassie’s anxiety soon turns into a bare-knuckled bitterness towards the person she holds responsible for the accident -- Taggart McGill -- her sister's constant companion. Now she’s torn between trying to understand the relationship…or ramming a red-hot curling iron down his throat.
When Taggart is asked to use his connections with the police to convince them that a death in the same accident that injured Becca was actually murder, Cassie decides to tag along. She discovers that Taggart is not who she thought he was, but also a secret organization exists at their high school responsible for even more deaths...all from a mysterious injection.
