"Blonde Ambition: An A List Novel" is the third book in a series written by Zoey Dean that chronicles the life of teenager Anna Cabot Percy. The series of books begins with Anna moving to Beverly Hills, California from the Upper Eastside of New York City. Anna finds herself in the middle of culture shock as she tries to adjust to the demands of Hollywood life and her new peers. In Blonde Ambition, Anna becomes even more initiated into Hollywood culture when she is given an internship on the set of a new television series. She sees firsthand the demands of a career in Hollywood and decides that it is probably not for her. Along the way, she meets new friends and learns more about the peers at her high school and the mysterious man who lives in her guest house.

At the beginning of the book, Anna is happily in a relationship with Ben Birnbaum. She struggles with guilt over the relationship that she has just ended with Adam Flood but finds that she is falling in love with Ben. Anna is fired from her internship at a powerful talent agency because her sister showed up drunk at an industry party. Before Anna can leave the building, however, an important agent named Clark Sheppard stops her and rehires her as his own intern. Anna begins working on the set of a new television pilot called "Hermosa Beach" and is immediately accepted by the group of writers and behind-the-scenes workers. She is especially drawn to the co-executive producer of the show, Danny Bluestone. He is a young, attractive man who flirts with Anna incessantly.

As Anna begins spending more time at work and with her father's driver, Django, her boyfriend Ben becomes increasingly jealous. He puts off going back to college at Princeton, telling Anna that he has worked out a deal with the Dean. When Anna discovers that he is close to being expelled and that the only reason he is staying behind is to be with her, she ends the relationship. Ben accepts this decision and returns to school. On her way home from dropping Ben off at the airport, Anna meets up with Danny and they go to a race track where she drives his fast sports car and realizes that she is falling for him.

Cammie Sheppard is the daughter of Clark Sheppard and is very jealous of Anna. Not only has Anna stolen all of her friends' time, but now she is being praised by her father. Cammie begins dating Anna's ex-boyfriend Adam and trying to develop a plan to ruin Anna's seemingly perfect life. Cammie uses information that she finds in her father's office to frame Anna for the crime of leaking information to the press about a cast member of "Hermosa Beach." When it is discovered that Cammie has been lying, her father cancels all her credit cards and has her luxury car towed.

Once Anna's name has been cleared of leaking the information, she is asked to return to be the intern on the show. She declines the offer and realizes that Hollywood is not the industry for her. She does return to the set one more time, however, to see Danny Bluestone. The two go to the beach and Anna realizes that while she is not in the market for a boyfriend, she is open to having fun with Danny and any other suitors.
