The First Trade Paperbacks from Mark London’s Underworld Coming Soon From Mad Cave Studios

FOR IMMEDIATE RELEASE:

JAN. 31, 2025, (PORTLAND, OR) — Mad Cave Studios is thrilled to expand Mark London’s Underworld with the first two paperback trade collections for REVOLUTION 9 (Apr. 23rd) and HOUR OF THE WOLF (Apr. 30th)!

Created and written by Mark London (Battlecats, Wolvenheart), with artwork by Carlos Reno (Revolution 9) and Danilo Beyruth (Hour of the Wolf), these books deliver two standalone stories filled with high-stakes action, supernatural intrigue, and noir-infused storytelling. Alliances will be tested and long-buried secrets will be revealed. Don’t miss the edge-of-your-seat thrills with these two amazing debut titles of the Underworld!

After years as an assassin for the Order of Nine-an ancient order dating back almost 3,000 years-Velveteen has turned her back on the very organization that saved her. Tasked with the murder of otherwise innocent hacker Jasper Dean, she sets off to save his life and discover the terrible secret that marked him for death. With the entire Order after them, Velveteen and Jasper must escape their grasp and prevent them from toppling society as we know it.

When Owen Blackwood is called across time to a seemingly normal home to destroy a haunted painting, it didn’t feel like anything out of the ordinary to this agent of Wolvenheart. Upon arrival, however, Owen finds himself trapped in the very painting he was called to destroy. With only a one hour window of time in which to operate, will Owen be able to save the family from certain death and destroy the painting? Or will he get lost in time and become a cross-dimensional walking ghost?

Both Revolution 9 and Hour of the Wolf are followed by the release of Exit City #4, which arrives in shops on Feb. 26. Each series in Mark London’s Underworld stands on its own, while also laying the groundwork for the highly anticipated series, Endless Night, launching in June!
