Autumn is an orphan who was recently in car accident forcing her to spend several months in a hospital. Autumn is left with amnesia and a severe limp that makes walking a struggle. The school promises a much needed change, but Autumn is worried how she will fit in when she does not even know who she is.

Autumn goes to her first round of classes but feels clueless when it comes to discussions of magic. To make things worse, everyone around Autumn seems familiar in some way, especially Amber, the head of students, and the attractive Master of Light, Beck Turner. Autumn also begins to have flashes of what could only be memories, but they are memories that seem to belong to someone else. At times, Autumn even sees someone else’s face in the mirror, a situation that makes her question her sanity.

Autumn’s roommate, Dawn, is an angry, selfish girl who is in the early months of pregnancy. Autumn tries to be nice, but she is put off immediately when Dawn shows no respect for Autumn's few belongings and refuses to respect Autumn’s bathroom time. Beck offers to help Autumn with Dawn, but when Autumn learns that Beck is the father of Dawn’s baby, it only further complicates things.

Autumn and Beck spend time together and begin to feel drawn to one another. However, when Autumn meets Decker at a football game and later on the Light campus, there is something about him that seems so familiar. Decker, too, is attracted to Autumn. This is something that shocks Decker and leaves him feeling guilty because he recently lost his counterbalance, or soul mate, and feels as though he is betraying her with his attraction to Autumn.

After Autumn gently ends things with Beck, he begins to date another young girl who just came to the school. Dawn becomes outraged when she hears that Beck is dating again.

Dawn and her friend lure Autumn out into the woods where they confront her about her relationship with Beck. An argument ensues and Dawn tells Autumn she is going to kill her. Dawn wants to kill Autumn so that Decker will turn on Beck. During the fight Autumn so enrages Dawn that she breaks the laws of Light magic and turns Dark.
