This is #6 in Zahn's Dragonback adventures. I love this series. It is a great combination of story and action and this book is the series conclusion. Jack Morgan and his symbiot Drakos (Drakos lives as a tatoo on Jack though he can become three dimentional) rush to save the rest for DRakos's people, the K'da. They get captured and escape. And in the end, the Human/K'da bond that Jack and Drakos have, save them from a genicidal weapon. Having said that, this book was not my favorite in the series. Not enough story. I know this book can not stand on its own for the TU. I vote Nay.
