Alexandra “Allie” Johnson, one of the novel’s primary protagonists, is 14 years old and has blond hair. She lives in Cape May, New Jersey, and has a father, a mother, and one sister. When she dies in the car accident with Nick, she doesn’t know what happens to her father, but she knows that her mom and sister are safe, as they stayed home. Allie knows that she is not unattractive, but she does not consider herself to be beautiful. However, she is very smart and intuitive and views situations practically and rationally. Allie’s pragmatic mind makes it difficult for her to adjust to Everlost, but her goal-oriented nature helps her rescue her friends against seemingly insurmountable odds. Allie can also be very blunt in her communications, but she doesn’t intentionally try to offend others. She just calls things as she sees them. Finally, Allie has a strong will, allowing her to skinjack: to take control of a living person’s mind and body because she can overcome their resistance to her intrusion.

As a protagonist, one of Allie’s main roles in the novel is to challenge Mary’s authority and power. She does so almost immediately upon meeting Mary by asking numerous questions about both the information and the omissions in Mary’s writings about Everlost.
