About the Book

The Obsidian Chamber

A tragic disappearance

After a harrowing, otherworldly confrontation on the shores of Exmouth, Massachussetts, Special Agent A.X.L. Pendergast is missing, presumed dead.

A shocking return

Sick with grief, Pendergast's ward, Constance, retreats to her chambers beneath the family mansion at 891 Riverside Drive --- only to be taken captive by a shadowy figure from the past.

An international manhunt

Proctor, Pendergast's longtime bodyguard, springs to action, chasing Constance's kidnapper through cities, across oceans, and into wastelands unknown.

But in a world of black and white, nothing is as it seems

And by the time Proctor discovers the truth, a terrifying engine has stirred --- and it may already be too late.
