Black Mirror

After my brother Daniel and I began at The Pettengill School, two years ago, I hadn't been able to stop our closeness from slipping away, until it was irretrievably gone.Now Daniel is dead of a massive, self-injected dose of heroin, and the only note he left behind was for his girlfriend, Saskia. My brother was in pain, and I noticed nothing. Nothing.__________Daniel had been deeply involved in Unity Service, the charitable group on campus. After his death, Frances decides to join the group and help with its good works. It's one way to make amends. But something's odd about Unity and its members.
