Amy Poeppel discusses her new book "Limelight" with Helen Little.

"Limelight" follows Allison Brinkley—wife, mother, and former unflappable optimist— as she discovers that a carefully weighed decision to pack up and move her family from suburban Dallas to the glittery chaos of Manhattan may have been more complicated than she and her husband initially thought.

Allison learns that New York is unruly and bewildering, defying the notions she developed from romantic movies and a memorable childhood visit. After a humiliating call from the principal’s office and the loss of the job she was counting on, Allison begins to accept that New York may not suit her after all.

When Allison has a fender-bender, witnessed by a flock of mothers at her son’s new school, she is led to the penthouse apartment of a luxurious Central Park West building and encounters a spoiled, hungover, unsupervised teenager who looks familiar. It doesn’t take long to recognize him as Carter Reid—a famous pop star who has been cast in a new Broadway musical. Through this brush with stardom, Allison embraces a unique and unexpected opportunity that helps her find her way in the heart of Manhattan.
