Shadowboxer — Trent Zelazny

Once a happy family man, Kealan now spends his days walking aimlessly and crashing in his friend's spare room. It never seems to matter how much he walks, because his shadow is always there. When he meets younger Valerie, an inquisitive and sensitive soul, a few rays of light begin to penetrate his dark curtains. But what about her jealous ex? How is it that some things inevitably tie together? And where does one's shadow lead to?
