Cath and Wren have been inseparable, but when they get to college Wren decides it's time to venture out on her own. Cath struggles to adjust to college life on her own and attempts to avoid any situations that are out of her comfort zone. One of Cath's passions is writing fanfiction for her favorite book series Simon Snow, which has manifested into her writing one of the most popular Simon Snow fanfictions online.
Something that I enjoyed while reading the novel was how it includes some of Cath's writing from her fanfiction. Fangirl (2013) brings a mix of family and internal struggles about coming of age with a sprinkle of romance and fanfiction.
