Dragon's heart

This book is a return to the planet of Austar IV and continues to follow the lives of Jakkan and Akki. Thus the original Pit Dragon Trilogy is now called the Pit Dragon Chronicles. The alien planet has many challenges and is richly described in believable detail. It also has dragons which, although reared, eaten and bet on in the fighting arenas, are much underestimated as a species. Jakkan and Akki know more about them than they want to become common knowledge because the greed of humans might then cause the dragons to be exploited until they are all killed.
