Are you a hero or a villain? Pick your path in Super You!, this action-packed, illustrated origin story where the reader – yes, that means YOU! – gets the power of flight and must decide, choice by choice, whether to use their abilities for good or evil. You thought you were in for an ordinary summer at science camp – that is, until you sneak into an off-limits area of the Center for Avian Science, get your hand scratched by a weird bird, and suddenly gain the power of flight! Now it's up to you to decide how to use the power: Will you fly out at night to save the day? Will you team up with the villainous Dr. Zeus, who bred the mutant bird and wants to take over the world with its powers? Or will you make the wrong choice and meet an ill-fated end? Follow the choices, pick your path, and fly toward your fate. This looks like a job for Super You!

Pakistan is the sixth most populous country in the world, the only Islamic state to have nuclear weapons, under military dictatorship for 33 of its 50 years in existence. Its 1000-mile border with Afghanistan is the likely hideout of Osama bin Laden--yet it is the linchpin in the United States' war on terror. With increasingly bold attacks by Taliban supporters in the border regions threatening to split the Pakistan army, with the only political alternatives as corrupt as the regime they seek to replace, and with a newly radicalized movement of lawyers testing its strength as champions of the rule of law, the chances of sustained stability in Pakistan look slim. Tariq Ali, long acknowledged as a leading commentator on Pakistan, combines deep understanding of the country with extensive firsthand research and unsparing political judgment to weigh the prospects of those contending for power today.--From publisher description.

Fly an airplane at a set attitude, airspeed, and power setting, and it does precisely what it is supposed to—every time. This book tells why and how “flying by the numbers” works, and gives the flight-tested numbers for precision performance in 27 of America's favorite small aircraft. For aircraft not included in this list, the book provides exact cockpit procedures for nailing down the numbers for any other light airplane.

"Much has been written about the famous conflicts and battlegrounds of the East during the American Revolution. Perhaps less familiar, but equally important and exciting, was the war on the western frontier, where Ohio Valley settlers fought for the land they had claimed -- and for their very lives. George Rogers Clark stepped forward to organize the local militias into a united front that would defend the western frontier from Indian attacks. Clark was one of the few people who saw the importance of the West in the war effort as a whole, and he persuaded Virginia's government to lend support to his efforts. As a result Clark was able to cross the Ohio, saving that part of the frontier from further raids. Lowell Harrison captures the excitement of this vital part of American history while giving a complete view of George Rogers Clark's significant achievements. Lowell H. Harrison, is a professor emeritus of history at Western Kentucky University and is the author or co-author of numerous books, including Lincoln of Kentucky, A New History of Kentucky, and Kentucky's Governors."

By the late 1930s air power had dramatically altered the strategic balance in Europe. But the seeds of the new order had been sown in World War I, when fledgling military air forces first emerged as adjuncts to the traditional armed services. Military leaders soon recognised its value as an aerial scout. And before long, fast fighter planes armed with machine guns were ordered into battle to support the armies of both the Allies and the Central Powers.
