If you’ve read the Short Story of the Day series so far, you know I love stories about monstrous women and girls. I shared Carrie Vaughn’s take on Alfred, Lord Tennyson’s “The Lady of Shalott” last year. Yesterday’s pick, Kelly Sandoval’s ‘What Sisters Take,” follows a teenager with a hidden twin who can only survive by killing her. Next up: “Sometimes Boys Don’t Know” by Donyae Coles.
