Witch Lights. Book Two of the Blackwater Lights Trilogy

The heir to H. P. Lovecraft by way of Dean Koontz, Michael M. Hughes returns with a new tale of paranormal horror-the hair-raising follow-up to Blackwater Lights.   Thrown together in the fight against a deadly supernatural conspiracy, Ray Simon, Ellen Davis, and Ellen's young son, William, are hiding out in Guatemala-one step ahead of Lily, a beautiful, wealthy sociopath who has become a conduit for bloodthirsty inhuman entities that seek to infiltrate our world.
Aiding this unholy plot is Ellen's own husband, an ex-Special Forces operative hell-bent on reclaiming his family and taking his revenge on Ray.   Long months on the run have taken their toll on Ray and Ellen, whose relationship is starting to fray, and William has lost all hope for a normal childhood. But when they let down their guard for an instant, things turn from bad to worse as Ray is separated from the woman and child he's sworn to protect.
  With nowhere else to turn, Ray calls upon the secretive occult Brotherhood, who have been desperate to recruit him. Help arrives in his old friend Mantu, an ex-comedian turned commando who claims to be on the side of the angels. But this situation is no joke. Ellen and William have been captured by a powerful drug lord-a violent sadist who offers to protect them for a price: Ellen's body .
