Into The Dragon's Nest (Seekers of the Lost Cavern #2)

It's not easy being Davern Cavern. Having only narrowly escaped a zombie tomb and his evil rival, Davern is still following the mystery trail left by his dad, the super-famous explorer who went missing months ago. Next stop: a cursed, ancient dragon's nest!
But first, Davern and his friends have to learn to fly a hovership, dodge a dumpling food-fight and deal with a real live dragon!
