When Fawn awakens in the middle of a burning house, her memories are completely gone. She doesn't know who or where she is. She doesn't even know her own name. Though two people come to her rescue who claim to be her parents, she doesn't recognize them. They don't look like her either. Yet she doesn't have any place to go, so she finds herself following them.
As Fawn grows accustomed to her life, though she still has no idea who she is, she meets her neighbor, Gavin. Gavin is tall and sweet with bright blue eyes. Unlike the rest of the world, he appears to understand her. He too has had a troubling past. The two of them form a tight alliance. It's them against the world. Soon Fawn comes to realize she has feelings for Gavin.
Unfortunately, that's when trouble rekindles in her home life. A strange man named Ark hunts after her, calling her Model 29. Soon she comes to realize she isn't what she appears. She's a robot, a robot hidden from society so her abilities wouldn't be used for evil. Now not only does Fawn have to be scared of Ark, but she has to worry about what this means for her and Gavin.
