Seaweed Brain and Voodoo Girl (A Percy Jackson x fem!OC Book)

Lucky Norwood, a demigod and a daughter of Hecate, always struggled in school and never felt like she belonged. It wasn't that she was an idiot, she was quite intelligent, but for some reason whenever she tried to apply her knowledge it never worked. When she read, the words seemed to rearrange themselves on the page. She could never focus and her mind was always running at a million miles a minute. She never had any friends until she met Grover Underwood. A weird quiet kid unless he was around Lucky. They'd been friends for a couple years. Her life seemed to be pretty normal.. until a manticore showed up at her school.
