The gwr. Shape-shifters. They are Beasts of legend. Inflamed by the moon and contained by silver. Known and shunned by good society for their blood-thirsty longings and uncontrollable emotions. Loving one is easy. Living with one is a different matter.

Poindexter Fitzhughes, renowned hero and scientist, learns just how much trouble a full-blooded gwr can be when he attempts to cure his lover, Lord Seth Maitland, of the disease. But when their backs are against the wall, the two learn to trust in each other, and more importantly, in their true natures, to prevail.
