The Dragon Factory by Jonathan Maberry

In Jonathan Maberry’s The Dragon Factory, Captain Joe Ledger and the Department of Military Sciences (DMS) race to stop a global catastrophe orchestrated by a group known as the Cabal. The antagonists, led by the Jakoby family and their allies, plan to unleash a genocidal "Extinction Wave" using advanced transgenics and pathogens developed from horrific Nazi medical research. Throughout the narrative, Ledger’s team encounters genetically modified monsters, ruthless assassins, and political treachery from within the United States government. The conflict culminates at a secret facility called the Dragon Factory, where a heroic clone of a Nazi scientist aids the DMS in thwarting the plague. Despite the ultimate success in stopping the countdown, the victory is bittersweet, marked by the tragic death of Ledger’s partner and lover, Grace Courtland. Following the battle, Ledger navigates physical recovery and profound grief as the world honors the fallen warriors who prevented a global ethnic cleansing.
