Audrey Clary, heiress and LeFay Academy's brightest alchemy student, is about to have her first and worst detention experience of all time. It's bad enough that she has to stay in detention during Sunflower Day—it's even worse that she's stuck in detention with the one and only Marion LaRue, the self-proclaimed “Chaotic Fireball Legend” of LeFay Academy.
Marion LaRue is not having a fun day at all. What was meant to be a harmless little fire turned into an explosion that has her stuck in detention, missing out on one of the rare opportunities for her to enjoy life outside the academy. And of course she just had to be stuck with Audrey Clary, of all the high class LeFay students she could be in detention with.
Determined to not miss out on the long-awaited festival, Audrey and Marion begrudgingly work together to escape detention and find their way to the festival. As they explore the city and celebrate the Sunflower Festival together, an old friendship is rekindled, and new feelings begin to bloom.
