Tunnels

ISBN: , SKU: , AUTHOR: Gordon, Roderick / Williams, Brian, PUBLISHER: Scholastic Paperbacks, The New York Times Bestseller The story of an outcast boy, his eccentric dad, and the scary underground world they discover through secret TUNNELS. 14-year-old Will Burrows has little in common with his strange, dysfunctional family. In fact, the only bond he shares with his eccentric father is a passion for archaeological excavation. So when Dad mysteriously vanishes, Will is compelled to dig up the truth behind his disappearance. He unearths the unbelievable: a secret subterranean society. "The Colony" has existed unchanged for a century, but it's no benign time capsule of a bygone era--because the Colony is ruled by a cultlike overclass, the Styx. Before long--before he can find his father--Will is their prisoner....

E. Aster Bunnymund and the Warrior Eggs at the Earth's Core!

ISBN: , SKU: , AUTHOR: Joyce, William, PUBLISHER: Atheneum Books for Young Readers, Average bunnies may hippity hop, but E. Astor Bunnymund (aka The Easter Bunny) is more the "hi-ya" type. Highly skilled in various martial arts--many of which he invented himself--and one of the oldest magical beings on earth, Bunnymund is the architect behind an unrivaled network of tunnels, which, combined with his supernatural speed, gives him secret access to almost anyplace on the planet. And though his tunnels come in handy when it's time to deliver mountains of candy and chocolate each year, E. Astor's favorite place to be is an underground metropolis on Easter Island where eggs are worshiped and Bunnymund is king. Except something is rotten in the state of Eggonooloo. Pitch, the Nightmare King, is on the attack, and if Bunnymund is going to successfully defend his royal guard of warrior eggs, he's going to need some help. Enter Nicholas St. North (from the first Guardians chapter book adventure) and his companions MiM and Sand Mansnoozy, and the stage is set for a battle of epic proportions.

Trains: A Photographer's Journey

ISBN: , SKU: , AUTHOR: Outerbridge, Graeme, PUBLISHER: ABRAMS, The powerful red electric engines of the Glacier Express easily climb the snow-covered Swiss Alps. Ancient steam engines of the Guayaquil & Quito Railway labor up the slopes of the Andes in Ecuador. Luxurious passenger carriages from another era amble across the great western desert of China at dusk. On the other side of the globe, the engineer of a sleek Amtrak engine waves a casual good-bye out the window of his massive machine as it leaves the station. Trains is a photographic journey to the world of railroads. For five years, photographer Graeme Outerbridge traveled the globe by rail photographing everything that caught his eye -- hulking engines, stations both lonely and bustling, dark tunnels, high-speed expresses, railroad workers, signs, signals, and the landscapes that the trains traversed. His images reveal the universal language of forms and colors that trains have created, and are as evocative as a lonesome whistle in the night.

Wish I Could Be There: Notes from a Phobic Life

ISBN: , SKU: , AUTHOR: Shawn, Allen, PUBLISHER: Viking Books, A droll, inquisitive, and poignant memoir of agoraphobia from a member of one of New Yorkas premier literary families Allen Shawn is afraid of heights, water, fields, parking lots, tunnels, and unknown roads. He avoids taking subways, using elevators, or crossing bridges. In short, he is afraid of both closed and open spaces and of any form of isolation. Yet this is a memoir of enormous bravery. Shawn grew up in a lively but mysterious world. He is the son of the famous, longtime "New Yorker" editor William Shawn and brother to the brilliant playwright and actor Wallace Shawn. His twin sister is autistic, and when they were eight years old, she was put in a home. Though it was kept from him until he was in his thirties, his father led a double life that introduced strict taboos to his household. Shawn examines these influences, his fatheras and motheras phobias, and his own struggle with agoraphobia with generosity, wit, and insight, attempting to decipher the psychological and biological puzzles that have plagued him for so long. Interwoven with both Freudian psychology and cutting-edge brain research, Shawn has written a profound examination of familial love and the universal struggle to face our demons.

Lockdown: Escape from Furnace

ISBN: , SKU: , AUTHOR: Smith, Alexander Gordon, PUBLISHER: Square Fish, Furnace Penitentiary: the world's most secure prison for young offenders, buried a mile beneath the earth's surface. Convicted of a murder he didn't commit, sentenced to life without parole, "new fish" Alex Sawyer knows he has two choices: find a way out, or resign himself to a death behind bars, in the darkness at the bottom of the world. Except in Furnace, death is the least of his worries. Soon Alex discovers that the prison is a place of pure evil, where inhuman creatures in gas masks stalk the corridors at night, where giants in black suits drag screaming inmates into the shadows, where deformed beasts can be heard howling from the blood-drenched tunnels below. And behind everything is the mysterious, all-powerful warden, a man as cruel and dangerous as the devil himself, whose unthinkable acts have consequences that stretch far beyond the walls of the prison. Together with a bunch of inmates--some innocent kids who have been framed, others cold-blooded killers--Alex plans an escape. But as he starts to uncover the truth about Furnace's deeper, darker purpose, Alex's actions grow ever more dangerous, and he must risk everything to expose this nightmare that's hidden from the eyes of the world.

Building Gotham: Civic Culture and Public Policy in New York

ISBN: , SKU: , AUTHOR: Revell, Keith D., PUBLISHER: Johns Hopkins University Press, In , the New York state legislature created Greater New York, a metropolis of three and a half million people, the second largest city in the world, and arguably the most diverse and complex urban environment in history. In this far-ranging study, Keith D. Revell shows how experts in engineering, law, architecture, public health, public finance, and planning learned to cope with the daunting challenges of collective living on this new scale. Engineers applied new technologies to build railroad tunnels under the Hudson River and construct aqueducts to quench the thirst of a city on the verge of water famine. Sanitarians attempted to clean up a harbor choked by millions of gallons of raw sewage. Economists experimented with new approaches to financing urban infrastructure. Architects and planners wrestled with the problems of skyscraper regulation and regional growth. These issues of city-building and institutional change involved more than the familiar push and pull of interest groups or battles between bosses, reformers, immigrants, and natives. Revell details the ways that technical values -- distinctive civic culture of expertise -- helped reshape ideas of community, generate new centers of public authority, and change the physical landscape of New York City. Building Gotham thus demonstrates how a group of ambitious professionals overcame the limits of traditional means of decision-making and developed the city-building practices that enabled New York to become America's first mega-city.
