It took only twenty-two minutes for Kirby Matheson to exit his car, march onto the school grounds, enter the gymnasium, and open fire, killing six and injuring five others.

But this isn't a story about the shooting itself. This isn't about recounting that one unforgettable day.

This is about one boy--who had friends, enjoyed reading, playing saxophone in the band, and had never been in trouble before--became a monster capable of entering his school with a loaded gun and firing bullets at his classmates.

Each chapter is told from a different victim's viewpoint, giving insight into who Kirby was and who he'd become. Some are sweet, some are dark; some are seemingly unrelated, about fights or first kisses or late-night parties. This is a book told from multiple perspectives--with one character and one event drawing them all together--by some of YA's most recognizable names.
