Ten years after the events of The Atonement Demon, Lilith's plan to rid the Earth of evildoers is progressing well. But her team of Demons are run off their feet, and the Astrals of Heaven can only do so much to help. There's still so much to do, so many abhorrent humans to annihilate.

A new radical idea comes to Lilith - one which involves seeing far into the future and stopping crimes before they happen.

Lilith needs the help of the All-seers - Astrals with a specific and special type of power. She already knows one All-seer, but the rest are spread far and wide... and not all of them want to be found.

Lilith puts together a team of trusted friends to seek out the All-seers. Some head for another soul sanctuary. Some head for another planet. Lilith heads for Supremasis, the domain of the Astral governing body. Can she get all the Astrals to help her and work together when they can't even trust each other?

Astrals Assemble is an adventure through space and two universes. It is the second book in the Astrals Series.
