In this thrilling panorama of real-life events, the bestselling author of Empire of Pain investigates a secret world run by a surprising criminal: a charismatic middle-aged grandmother, who from a tiny noodle shop in New York’s Chinatown managed a multi-million dollar business smuggling people. “Reads like a mashup of The Godfather and Chinatown, complete with gun battles, a ruthless kingpin and a mountain of cash. Except that it’s all true.” —Time Keefe reveals the inner workings of Sister Ping’s complex empire and recounts the decade-long FBI investigation that eventually brought her down. He follows an often incompetent and sometimes corrupt INS as it pursues desperate immigrants risking everything to come to America, and along the way, he paints a stunning portrait of a generation of illegal immigrants and the intricate underground economy that sustains and exploits them.

This book is a comprehensive identification guide to the 222 species of fishes in Florida’s fresh waters. Each species is presented with color photographs, key characteristics for identification, comparisons to similar species, habitat descriptions, and dot distribution maps. Florida's unique mix of species includes some of the world's favorite sport fishes, the Tarpon and Largemouth Bass. This guide also features three species native only to Florida—the Seminole Killifish, Flagfish, and Okaloosa Darter—and the smallest freshwater fish in North America, the Least Killifish. Ranging from the panhandle to the Everglades, their habitats include springs, creeks, rivers, lakes, ponds, swamps, marshes, and man-made canals. As Florida's human population grows, the state's freshwater environments are being changed in ways that threaten its native fishes. This book provides important information on the diversity, distribution, and environmental needs of both native and nonindigenous species, helping us monitor and take care of Florida's water and its aquatic inhabitants.
