After a murderous attack at the Los Angeles Zoo, young evolutionary biologist Jackson Oz is convinced his findings are correct: Animal attacks on humans are rising at an alarming rate. Thus far, convincing the powers that be has been to no avail. Jackson finds out just how true his contention is when he travels to Africa and observes the aftermath of a massacre by lions that is not only unprecedented but also terrifying in its ferocity. Oz’s only ally is Chloe Tousignant, a French ecologist and witness to the carnage whom he rescues from an assault by crocodiles! How can they make the leaders of the world believe in the encroaching danger?

When Oz and Chloe arrive back in New York they’re horrified to see dogs hunting in packs…rats striking out on city streets…and gentle pets turned into predators whose reliance on cunning and apparent planning have humans on the run. Unfortunately there’s no place to hide. Will Oz and Chloe discover what’s causing this descent into madness before it’s too late?

James Patterson’s unputdownable, white-knuckle tales have made him a living legend. This book surpasses them all. Zoo is the thriller Patterson was born to write.
