Zoo

Once in a lifetime, a writer puts it all together. This is James Patterson's best book ever.
For 36 years, James Patterson has written unputdownable, pulse-racing novels. Now, he has written a book that surpasses all of them. ZOO is the thriller he was born to write.
World
All over the world, brutal attacks are crippling entire cities. Jackson Oz, a young biologist, watches the escalating events with an increasing sense of dread. When he witnesses a coordinated lion ambush in Africa, the enormity of the violence to come becomes terrifyingly clear.
Destruction
With the help of ecologist Chloe Tousignant, Oz races to warn world leaders before it's too late. The attacks are growing in ferocity, cunning, and planning, and soon there will be no place left for humans to hide.
"LOCATED IN GRIFFITH Park, a four-thousand-acre stretch of land featuring two eighteen-hole golf courses, the Autry National Center, and the HOLLYWOOD sign, the Los Angeles Zoo and Botanical Gardens is more of a run-down tourist attraction than a wildlife conservation facility. Funded by fickle city budgets, the zoo resembles nothing more than a tired state fair. Garbage cans along its bleached concrete promenade spill over. It is not uncommon to catch the stench of heaped dung wafting from cages where ragged animals lie blank-eyed, fly-speckled, and motionless beneath the relentless California sun."
