Dragon Tears is a 1993 paranormal/horror novel by the best selling author Dean Koontz. The opening line sets the tone: "Tuesday was a fine California day, full of sunshine and promise, until Harry Lyon had to shoot someone at lunch." The book covers the events of several seemingly unassociated people and how that one day gets worse and worse, culminating in a hopeless situation. With real monsters and magic to deal with, all are physically and mentally taxed to their limits. Source: Wikipedia (en)
