Carbon Grey: OmnibusHardcover, 17 May 2022

Twins are born to a noble family -- Mathilde and Giselle, the Sisters Grey. For centuries, the Greys have protected the ruler of Mitteleuropa, but this is a different time -- it is the dawn of the Industrial Age and a great war rages. When the Kaiser is found dead, Giselle is accused of his murder. Pursued by her sisters and hunted by the enemy, Giselle must unravel the prophecy of the Carbon Grey before history itself is rewritten.

Collecting the complete CARBON GREY graphic novel series by Hoang Nguyen, Paul Gardner, Khari Evans, and Kinsun Loh, this 304-page omnibus has been re-edited and remastered to tell the entire saga of the Sisters Grey in a new edition designed to open the doors for an expanded universe through tabletop role-playing and other planned supplemental releases.
