Nightwalker - Book 5 Echoes of the Damned Series

The celestial-infernal entity known as The Balance had faced countless threats to the cosmic order they were tasked with upholding, but a new darkness loomed on the horizon. A summons from the remote Area 59 region hinted at a terrifying new menace - the Nightwalkers.

Driscol, the powerful demon lord whose infernal essence comprised half of The Balance, could sense the urgency rippling through the veil separating realms. Alatha, the angelic counterpart whose celestial light had once been his adversary, shared his trepidation through their unbreakable bond.

As guardians of the veil, they had no choice but to heed the call. Manifesting in Area 59, they found a scene of unspeakable carnage. The Balance soon realized these were no ordinary attacks. The Nightwalkers were something new, something that seemed to transcend the boundaries of the known realms.
