This second book in a sparkling middle grade series that gives a fresh take on The Baby-Sitters Club follows Gigi and her friends to New York City as they attend the art camp of their dreams. Gigi Shin is looking forward to her best summer ever: not only did she get accepted to the prestigious Starscape Art Academy in New York City, but so did all her friends and fellow Ace Squad members! Plus, Gigi's art idol, Christiana Moon, is going to be a guest lecturer and Gigi is determined to make a great impression.

But as soon as they land in NYC, things don't exactly go to plan. Instead of being able to room with each other, the girls are all assigned to room with other attendees; Gigi is paired with Sohee, who doesn't seem too excited to have Gigi as a roommate. The workload is heavy, and while the teachers are all experts in their field, they aren't exactly the best instructors--including Gigi's idol, Christiana, who's dismissive when Gigi asks her for advice.

When all the attendees are given a huge opportunity to showcase their work, Gigi and her friends are determined to turn things around and make the best of camp, using the city for inspiration. With the help of some unexpected allies, can Gigi prove to everyone--and herself--that she has what it takes?
