"For most kids, catching fireflies is just a fun activity. For twelve-year-old Serwa Boateng, it's a matter of life or death. That's because she knows some fireflies are really adze, shapeshifting vampires from the forests of southeastern Ghana. For generations, a secret society of Slayers like Serwa and her parents have protected the world from their threats. But when a group of adze led by a powerful witch destroy destroys her home, do Serwa's parents take her with them on their quest to defeat her? No. They dump Serwa with her aunt in the middle of Nowheresville, Maryland. Now, instead of crossbows and battle armor, she's dealing with mean girls and algebra. Just as Serwa starts to get the hang of being a "normal" kid, an adze infiltrates her school. It's up to her to assemble a team of her classmates and get them into monster-fighting shape before they all become firefly food. Because seventh grade is hard enough without throwing vampires into the mix." - Cover.
