Before there was a Mysterious Benedict Society there was simply a Boy Named Nicholas Benedict. Nine-year-old Nicholas Benedict has more problems than most children his age. Not only is he an orphan with an unfortunate nose, but also he has narcolepsy, a condition that gives him terrible nightmares and makes him fall asleep at the worst possible moments. Now he's sent to a new orphanage, where he encounters vicious bullies, selfish adults, strange circumstances - and a mystery that could change his life forever. Luckily, he has one important thing in his favor: He's a genius. On his quest to solve the mystery, Nicholas finds enemies around every corner, but also friends in unexpected places - and discovers along the way that the greatest puzzle of all is himself.

The best-selling author of E=mc2 weaves tales of romance, divine inspiration, and fraud through an account of the invisible force that permeates our universe - electricity - and introduces us to the virtuoso scientists who plumbed its secrets. For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders - complete with roller coasters and radar, computer networks and psychopharmaceuticals. In Electric Universe, the great discoverers come to life in all their brilliance and idiosyncrasy, including the visionary Michael Faraday, who struggled against the prejudices of the British class system, and Samuel Morse, a painter who, before inventing the telegraph, ran for mayor of New York City on a platform of persecuting Catholics. Here too is Alan Turing, whose dream of a marvelous thinking machine - what we know as the computer - was met with indifference, and who ended his life in despair after British authorities forced him to undergo experimental treatments to “cure” his homosexuality. From the frigid waters of the Atlantic to the streets of Hamburg during a World War II firestorm to the interior of the human body, Electric Universe is a mesmerizing journey of discovery.

A classic in the making - an account of the biggest year in birdwatching history. In the USA, some 50 million people lay claim to being bird-watchers or “birders,” spending billions of dollars on birding-related travel and membership fees every year. A select, and utterly obsessed, few compete in one of the world’s quirkiest contests - the race to spot the most species in North America in a single year. And 1998 wasn’t just a big year. It was the biggest. The Big Year is Pulitzer Prize-winner Mark Obmascik’s account of what was to become the greatest birding year of all time. It was freak weather conditions that ensured all previous records were broken, but what becomes clear within the pages of this classic portrait of obsession is that while our feathered friends may be the objective of the Big Year competition, it’s the curious activities and behavioral patterns of the pursuing “homo sapiens” that are the real cause for concern. It is a contest that reveals much of the human character in extremes. Such are the author’s powers of observation that he brilliantly brings to life and gets under the skin of these extraordinary, eccentric and obsessive birders while empathizing with and eventually succumbing to the all-consuming nature of their obsession. The result is a wonderfully funny, acutely observed classic to rank alongside the best of Bill Bryson.

The most important reformer and innovator in American religious history, Joseph Smith has remained a fascinating enigma to many, both inside and outside the Mormon Church he founded. Born in 1805, Smith grew up during the "Second Great Awakening", when secular tumult had spawned radical religious fervor and countless new sects. His contemplative nature and soaring imagination were nurtured in the close, loving family created by his deeply devout parents. His need to lead and be recognized was met by his mission as God's vehicle for a new faith and by the hundreds who, magnetized by his charm and charismatic preaching, gave rise to the Mormon Church. Remini's vital portrait contextualizes Smith's enduring contribution to American life and culture within the distinctive characteristics of an extraordinary age.
