Extinction was just the beginning. In this pulse-pounding adventure, a Wyoming game warden encounters something she never thought possible: a real-life saber-tooth tiger. For two decades, Sam Brodie has never let a poacher get away or come across an animal print she couldn't identify... until she tracks a vicious predator that went extinct in the Ice Age. But when Sam reaches the tiger, she finds herself in the crosshairs of ruthless hunters intent on having no witnesses. With killers on her tail, she uncovers a chilling plot to clone extinct predators for a barbaric "extreme" hunting experience for the wealthy elite. But these creatures are not simply clones; they're bigger, meaner, and pose an unparalleled danger to the world's ecological balance. With the fate of the world hanging in the balance, Sam and her team must race to stop the mastermind before he unleashes his ultimate creation. Can Sam stop him, or will humanity face its own extinction? Join the hunt and find out in this dark science thriller!
