The Obsidian Chamber

A TRAGIC DISAPPEARANCE

 

After a harrowing, otherworldly confrontation on the shores of Exmouth, Massachusetts, 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 . . .
