Dragon Delasangre Series by Alan F. Troop

Here, at last, are the confessions of one Peter DelaSangre, who tells of his life on an island off the coast of Miami...of his lonely balancing act between the worlds of humans and dragons...and of the overwhelming need that gives his life purpose: To find a woman of his own kind...

The confessions of the dragon Peter DelaSangre continue four years after the murder of his beloved wife.

Peter DelaSangre now enjoys a peaceful existence with his family on a private island retreat just off the coast of Miami. Then he receives an unexpected visitor named Lorrel, a member of a sea-dwelling dragon race who will force Peter to face his bloodline's secret past-revelations that may separate Peter from his family forever.

A vessel bearing twelve mysterious passengers arrives at a marina near Peter DelaSangre's secluded island home, heralding the arrival of more sinister events-including the kidnapping of Peter's daughter and a corporation's attack against the family fortune. Now, Peter must uncover the ties that binds these misfortunes together, before it's too late.
