Summary: In an ugly world ruled by demons where humans are enslaved and hunted and killed, Dean must find his way through blood, loss and power. In this journey he realises that whether eternal or ephemeral, beauty can be found anywhere and everywhere. Sometimes it's in the laughter of his brother and sometimes in the warmth of his father's eyes. Other times, Dean remembers his mother, and how she always told him that all his wishes could come true one day, if he just thought of it hard enough.
Eventually when everything starts to crumble beneath his feet Dean is forced into a desperate fight to keep his family together. And in this journey he finds another thing that he never expected to: love in the arms of an angel.
