To his shock, a face match reveals the stranger's name: Ryker Kane, heir to a powerful corporate empire… and a student at an elite, almost mythical academy. It’s not quite a high school, not quite a university—more like something in between. Something hidden.One of Ryker’s photos contains a strange symbol that leads Aiden to an encrypted link.

What could one drop of blood hurt?He sends it, expecting nothing.A week later, an ornate envelope arrives.
