"Sisterhood, food, and spelling... that's all that matters in life." Laura Cooper has always felt like a half, and her other side is her twin sister, Allie. Two of everything. Two beds, two pairs of jeans, two homework assignments, two times the fun. But there's only one Spelling Bee Champ. The girls discover they have a knack for Spelling during a preliminary bee... but can the Cooper twins go all the way? As they rely on nerve, skill, and most of all each other, to climb their way to become the Spelling Sisters, tension between the girls rises. At the National Spelling bee, only one contestant can shine. Only one half of the Cooper twins. One must step in front of the other, causing the other one to not be seen. Causing a total eclipse.
