Sadie Wen is perfect on paper: school captain, valedictorian, and a "pleasure to have in class." It's not easy, but she has a trick to keep her model-student smile plastered on her face at all times: she channels all her frustrations into her email drafts. She'd never send them of course — she'd rather die than hurt anyone's feelings — but it's a relief to let loose on her power-hungry English teacher or a freeloading classmate taking credit for Sadie's work.

All her most vehemently worded emails are directed at her infuriating cocaptain, Julius Gong, whose arrogance and competitive streak have irked Sadie since they were kids. "You're attention starved and self-obsessed and unbearably vain . . . I really hope your comb breaks and you run out of whatever expensive hair products you've been using to make your hair appear deceptively soft . . ."

Sadie doesn't have to hold back in her emails, because nobody will ever read them . . . that is, until they're accidentally sent out.

Overnight, Sadie's carefully crafted, conflict-free life is turned upside down. It's her worst nightmare — now everyone at school knows what she really thinks of them, and they're not afraid to tell her what they really think of her either. But amidst the chaos, there's one person growing to appreciate the "real" Sadie — Julius, the only boy she's sworn to hate . . . .

A deep-time history of animals and humans in North America, by the best-selling and award-winning author of Coyote America.

In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness.

Distinguished author Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America—a place shaped both by its own grand evolutionary forces and by momentous arrivals from Asia, Africa, and Europe. With portraits of iconic creatures such as mammoths, horses, wolves, and bison, Flores describes the evolution and historical ecology of North America like never before.

The arrival of humans precipitated an extraordinary disruption of this teeming environment. Flores treats humans not as a species apart but as a new animal entering two continents that had never seen our likes before. He shows how our long past as carnivorous hunters helped us settle America, initially establishing a coast-to-coast culture that lasted longer than the present United States. But humanity's success had devastating consequences for other creatures. In telling this epic story, Flores traces the origins of today's "Sixth Extinction" to the spread of humans around the world; tracks the story of a hundred centuries of Native America; explains how Old World ideologies precipitated 400 years of market-driven slaughter that devastated so many ancient American species; and explores the decline and miraculous recovery of species in recent decades.

In thrilling narrative style, informed by genomic science, evolutionary biology, and environmental history, Flores celebrates the astonishing bestiary that arose on our continent and introduces the complex human cultures and individuals who hastened its eradication, studied America's animals, and moved heaven and earth to rescue them. Eons in scope and continental in scale, Wild New World is a sweeping yet intimate Big History of the animal-human story in America.
