The Dwarons of Divinia by Grant, Paul le plus cher B. F. NEUF

This is the first book in a series of four books about Dwarons - a weaker, smaller variety of dragons who were treated as misfits; rejected and excluded by le plus cher the fierce and more powerful dragons.

The dragons exiled the in-any-way different Dwarons to the island of Divinia where they evolved and changed into a peaceful, non-firebreathing variety of dragon, surviving peacefully on Divinia long after the dragons who had excluded them had become extinct - that is until the world outside Divinia began to encroach on their peaceful existence!

Loosely based on the life of a Norse explorer, this book tells the story of one young man who is saved from shipwreck on the island of Divinia and how his life is changed for the better.
