Void Nexus: Ascension by Leo Dan Casther

Four months have passed since the events of 'Communion'. Moritz, Eréndira, and their companions are determined to eradicate what remains of the Void and have been honing their skills. However, the world they now inhabit feels unlike the one they once knew.

After a period of relative peace, a sudden visit and warning from a being beyond time and space will force them all to reconsider their plans. Now, the group of former witch hunters, the Order, their allied deities, their old and new enemies, and everyone on the planet and beyond must begin a race against time, to reclaim their right to exist.

With God absent and lost in the void, the world will grapple with whether to adhere to His old precepts or create new ones, but above all, the greatest dilemma will be choosing the one entrusted with this latter task.
