From A MOTHER'S RECKONING:

A day does not pass that I do not feel a sense of overwhelming guilt--both for the myriad of ways I failed Dylan and for the destruction that he left in his wake. . . I think often of watching [fourth-grade] Dylan do origami. . . I loved to make a cup of tea and sit quietly beside him, watching his hands moving as quickly as hummingbirds, delighted to see Dylan turn a square of paper into a frog or a bear or a lobster. I'd always marvel at how something as straightforward as a piece of paper can be completely transformed with only a few creases, to become suddenly replete with new significance. Then I'd marvel at the finished form, the complex folds hidden and unknowable to me. In many ways, that experience mirrors the one I would have after Columbine. I would have to turn what I thought I knew about myself, my son, and my family inside out and around, watching as a boy became a monster, and then a boy again."

From Andrew Solomon's introduction:

[Sue Klebold] was an ordinary suburban mother before Columbine... but in the wake of that tragedy, she found the strength to extract wisdom from her devastation... The ultimate message of this book is terrifying: you may not know your own children, and, worse yet, your children may be unknowable to you. The stranger you fear may be your own son or daughter.”
