Friends With Boys by Faith Erin Hicks
February 28th, 212 from First Second Books
After being homeschooled her entire life by her now estranged mother, Maggie starts her first day of 9th grade at a public high school. As she walks through the cemetery on the way to school, she meets up with an old acquaintance...a ghost. Maggie has been followed by this curly haired woman in a long, white gown for years, but lately she has been following Maggie home. At school, she befriends a quirky girl, Lucy, with half a shaved head and piercings and her quiet mohawked older brother, Alistair. Eventually, Maggie confides in Lucy and Alistair about her otherwordly follower and they devise a plan to help the ghost settle her "unfinished business" and send her on her merry way. Everything comes to a head when the plan goes horribly wrong. Words are said, punches are thrown, and the cops are called.
