Aunt Emma is Kelley's aunt. Aunt Emma raised Kelley after Kelley's parents died. Aunt Emma is very protective of Kelley, so she is less than thrilled that Kelley has moved to New York City to pursue her dreams of acting. Aunt Emma turns out to be Sonny Flannigan's biological mother.
When Sonny is stolen from Emma, she seeks revenge. She sneaks into the Otherworld, with the help of Bob, to steal Auberon's daughter from him. That daughter is Kelley. When Emma gets back from the Otherworld with Kelley, the parents that end up adopting Kelley find Emma wandering in Central Park. They take her home and then end up adopting Kelley.
By the end of the novel, Kelley knows the truth. Emma and Sonny are also reunited to restart their relationship as mother and son.
