After decades, the Mexican civil war is all but over, but a review of captured documents reveals a secret—the now-deceased guerrilla leader of La Fuerza was, for over a decade, stealing from his own revolution. Billions of dollars are missing—enough to sustain the war effort, if discovered, or maybe even topple the struggling Mexican government. Private contractor Seamus O'Malley, leading an elite team, is tasked with locating and retrieving the cash.



The Mexican Attorney General thinks the money is hidden somewhere near Xicotepec, a remote mountainous town that has lately been dealing with mysterious animal attacks. The locals think it might be jaguars. The truth is far more terrifying.



Meanwhile, an international team of scientists returns to Pangaea, the abandoned dinosaur park. They've discovered a secret that has been hidden there for twenty years, something that could revolutionize medicine and is sure to earn someone a Nobel Prize once they find it . . . provided nothing unexpected happens.



But neither group will be able to escape the bloody echoes of Pangaea, where nothing ever goes as planned . . .
