Why? ($14) by Adam Bex
Amazon's Description: "When supervillain Doctor X-Ray swoops in threatening to vanquish an innocent crowd, the only one brave enough not to run away is a little girl, who asks him simply, 'Why?' He is taken aback—but he answers. She keeps asking. And he keeps answering — until a surprising truth is uncovered, and the villain is thwarted."
