Charlie Nealon

Untouched
During Sienna's first "date" with Zack at Eden Prairie Center, Sienna sees a woman with dark hair in a revealing red dress and thinks it's her mother. Once she gets up close she realizes it is not her mother. Sienna notes that the woman is middle-aged, wears a lot of makeup, and sways her hips when she walks.

At the end of the book Sienna returns to the mall to shop for clothes after accepting the job with The Directorate and receiving her first paycheck. She sees the same woman in a different red dress. The woman approaches Sienna and introduces herself as Charlene "Charlie" Nealon, younger sister of Sierra and aunt to Sienna.
