Corin is drawn even further into the realms of magic and the otherworld. Through his spirit guide the Oak King, Corin is gifted the power to mind meld with animals. But his otherworld guide also reveals all is not well in his realm. There are rebellious factions in the otherworld who seek revenge from humans for the damage they are doing to the natural world. This war between the realms causes climate change to escalate beyond all reckoning, threatening the very existence of the human race.
The author now moves to a possible future where sea levels have risen, causing Ireland to become an archipelago of islands. But Corin is now mentored by the mysterious Uncle Dafydd. Through him he learns the true function of the megalithic monuments laid down by the ancient race of the Tuatha de Danann. To save the human race from total extinction, they must find the missing Syrinx and rescue the god Pan, who has been entombed in a tree.
