Moore, Oklahoma (CNN) -- Five days ago, Miranda Mann huddled in a science classroom at Southmoore High School. She should have been filed with pride, relief and excitement about her upcoming graduation. Instead, she was filled with fear as a devastating tornado powered through her central Oklahoma city. The 18-year-old has been literally picking up the pieces of her life since. Her house was unrecognizable, except for her and her mother's cars, after the twister destroyed it Monday. Her family sifted through rubble and salvaged some things, only to see many of them -- such as her prized book collection -- ruined by torrential rains.

Like Mann, he's a @placeholder senior; like her, he no longer has a place to call home.
