Where does evil come from? Why do children from ordinary families turn into monsters? And, most importantly, will they ever be punished for their monstrous actions?

Daryl Greer is only sixteen. He lives with his mom and dad in Kansas and loves bats and being alone. He seems strange to those around him, sometimes even dangerous, although not enough to pay special attention to him. But everything changes one terrible day. The very day when Daryl decides to commit a terrible crime, choosing his own parents as victims.

The reader will have to not only understand what happened, but also understand: how did it happen that the family did not notice the wolves at the door - signals that would could have warned of an impending tragedy.
