My name is not Mara Dyer, but my lawyer told me I had to choose something. A pseudonym. A nom de plume, for all of us studying for the SATs. I know that having a fake name is strange, but trust me-it's the most normal thing about my life right now. Even telling you this much probably isn't smart. But without my big mouth, no one would know that a seventeen-year-old who likes Death Cab for Cutie was responsible for the murders. No one would know that somewhere out there is a B student with a body count. And it's important that you know, so you're not next.
