As the moons above the Dim City fast approach the rare alignment called the Syzygy of Seven, The Garret survivors seek a legendary King who perhaps alone can prevent the destruction not only of the Yellow Corridor and its attendant worlds but possibly of the Earth as well.

The Thirteen are alive! Though the Ravenwood disaster hurled them into a blasted world, through luck and ingenuity they have survived. Norma has managed to send a message back – “We live!” – and The Garret Gang has replied. Can they be closer to bringing the lost ones home?

Banned from chemistry, Jack has found new employment doing home repair and remodeling. With sight, self-confidence and income restored he’s asked Suzanne to marry him…and she’s said “yes”!

First, though, they must pass or defeat the wakened guardians of the ancient city…and quickly! For soon comes a rare, potent but all too brief alignment of suns and moons, the Syzygy of Seven, and only while it lasts can Mel hope to fulfill her mission from the Guardians.

To help, another has joined them: Cissy’s friend Chuck Taylor, a brilliant engineering student now mind-bonded to her by Jack’s drug. Can he help the growing coven find the Tree, and Mel pass the Watchers, before the Syzygy ends?
