Petunia sends a baby Harry to her aunt, living in America, Caroline Evans. Some years later, Caroline becomes GLaDOS, and only Harry stops her from her rampage. Now, Harry is eleven, and he's heading to Hogwarts. Of course, with an amoral scientist/computer for a great-aunt and a mute big sister, the question is not whether he is ready for Hogwarts. Is Hogwarts ready for him?
