A girl who is about to realize that she can define who she is, when her older sister Bex returns home with a revelation, Andi is left with many questions that jump start her self-discovery. She has her sounding boards and best friends Cyrus and Buffy by her side, and each are simultaneously attempting to understand who they are and how they might fit in the world.
Andi was raised in a loving yet overprotective home. Now, with Bex’s encouragement, she begins to step outside her comfort zone, particularly when it comes to approaching the most intriguing guy at Jefferson Middle School—Jonah Beck, whom she quickly realizes is dating a high school girl, Amber. Andi proves that her greatest strengths may be how she accepts life’s unpredictability with optimism. She also finds solace by tapping into her creativity in her backyard hideaway, the Andi Shack.
