"Rye stands before three Doors, about to step out into the unknown. He's lived his whole life safe inside the enormous wall that rings the city of Weld and protects against the terrible dangers outside. Now, Weld is under attack from skimmers, flying beasts the kill in the night. If the enemy sending the skimmers isn't found, the citizens of Weld are doomed.
But that’s not why Rye has volunteered on a mission to leave Weld and stop the skimmers. His real goal is to find his two older brothers, who volunteered before him and never returned. Now Rye must open a Door and begin a perilous quest that could save his brothers... or cost his life."
While the Lord of Shadows mentioned in this book is the same character as the Shadow Lord found in the Deltora Quest series, the characters of Nanion and Ethena found in this book are ancestors of the Nanion and Ethena of the Deltora Quest series.
The people Fleet are the ancestors of the people of D'Or.
The golden Door leads to a thousand years back into past, to the time when Queen Adina ruled Deltora and the people of Fleet were migrating to Deltora.
The book along with the rest in the Three Doors trilogy include several references to the Deltora Quest series, as it is set in the same world.
