Keep your eyes closed. That's how you survive in Florida, FL. Florida, FL: small, slightly run down, and sitting right next to a rift between worlds. Called the borderline by the locals, all anyone knows for sure is that it ate Momo Kasahara six years ago and is best left alone. Lin, a high school dropout now working at the world's weirdest corner store, Midnight Morton's, tries not to dwell on the missing girl she might have loved. With no real future in sight, Lin accepts overnight shifts, saves her pennies, and ignores the faceless entity seeking instant oatmeal. But when a grown-up Momo appears one night like a ghost in the snack aisle, everything changes. Lin is sure that finding her will cure the strange gloom that's been hanging over her and her town for so long. Momo's twin brother Bo just wants his family whole again, and budding paranormal vlogger Julien True sees his chance to shoot the pilot episode of his dreams. Together the three of them must learn how to cross over borderline, unraveling the terrible secrets of Florida one by one until their rescue mission is successful. Because Momo is not a ghost at all. She's very much alive--and angry.
