Chains of Shadow

From publisher blurb: Some ghosts are not content to lurk in the shadows as mere haunts and corrupters. They peer deep into a twilight world, one that conceals mysteries and powers beyond the knowledge or ability of the corporeal. Chains of Shadow provides eighteen new feats specifically designed for such ghosts; those who desire to dwell between light and dark, take and shape the shadows around them, and master umbral powers of both creation and destruction.
