Spoiler alert-o-meter: Mild to medium spoiler alerts ahead.
In Matt Reeve's Let Me In a 12-year-old boy, Owen, living through a snow-filled Los Alamos winter with his not-quite-there mother, falls for a beautiful new neighbor girl, Abby. Abby's different. She walks around in the snow wearing a simple black skirt and no shoes. She completes a Rubik’s Cube in a snap. She doesn’t go to school. She’s been, as she says, “12 for a very long time.” Okay, no secret—she’s a vampire, doomed to live an eternal life as a blood-eater.
