Book Description
Gossamer Odyssey tells the story of the historic flight of the Gossamer Albatross, a spindly, feather-light craft which on June 2, 1979, became the first human-powered aircraft to cross the English Channel. Author Grosser covers the history of human-powered flight including the various unsuccessful efforts in Europe following World War I as well as programs in England and Japan following World War II. The development and flight of the first successful human-powered aircraft, the "Gossamer Condor, is covered in great detail. Grosser, who was a member of the "Gossamer Albatross team, provides an expert account that is fully accessible to the layperson and demonstrates how the channel crossing was an incredibly challenging undertaking despite the earlier success of the "Condor.

Book Description
Join everyone's favorite succubus and her half-fiend boyfriend—introduced in the War of the Spider Queen series—in the first installment of their own exciting trilogy Aliisza and Kaanyr Vhok return from their attempted invasion of Menzoberranzan feeling the sting of defeat. No sooner have they licked their wounds than they have set their sights on a different quest: conquer Sundabar, one of the wealthiest military cities in Faerûn and the home of Vhok’s foe. But before Aliisza can complete her mission in that besieged city, she finds herself in the one place a demon would never want to go, no matter how sure she is of her wits and cunning: the very heart of Celestia. Trapped beyond the gates of heaven, Aliisza reflects upon her past—a past riddled with selfishness and crime—and begins to see the error of her ways. As she learns more about herself, coming more fully into her own, she finds allies where she least expects.

Book Description
What do a bumble bee and a 747 jet have in common? It’s not a trick question. The fact is they have quite a lot in common. They both have wings. They both fly. And they’re both ideally suited to it. They just do it differently. Why Don’t Jumbo Jets Flap Their Wings? offers a fascinating explanation of how nature and human engineers each arrived at powered flight. What emerges is a highly readable account of two very different approaches to solving the same fundamental problems of moving through the air, including lift, thrust, turning, and landing. The book traces the slow and deliberate evolutionary process of animal flight—in birds, bats, and insects—over millions of years and compares it to the directed efforts of human beings to create the aircraft over the course of a single century. Among the many questions the book answers: Why are wings necessary for flight? How do different wings fly differently? When did flight evolve in animals? What vision, knowledge, and technology was needed before humans could learn to fly? Why are animals and aircrafts perfectly suited to the kind of flying they do? David E. Alexander first describes the basic properties of wings before launching into the diverse challenges of flight and the concepts of flight aerodynamics and control to present an integrated view that shows both why birds have historically had little influence on aeronautical engineering and exciting new areas of technology where engineers are successfully borrowing ideas from animals.

Book Description
A novel “as haunting as a dream” from the New York Times-bestselling, Newbery Medal-winning author of The Giver (Kirkus Reviews, starred review). Where do dreams come from? What stealthy nighttime messengers are the guardians of our most deeply hidden hopes and our half-forgotten fears? This imaginative novel confronts these questions and explores the conflicts between the gentle bits and pieces of the past that come to life in dream, and the darker horrors that find their form in nightmare. In a haunting story that tiptoes between reality and fantasy, two people—a lonely, sensitive woman and a damaged, angry boy—face their own histories and discover what they can be to one another, renewed by the strength that comes from a tiny, caring creature they will never see. “Lyrical, richly descriptive prose ushers readers into a fascinating parallel world inhabited by appealingly quirky characters.”—Publishers Weekly (starred review) “A beautiful novel with an intriguing premise.”—School Library Journal (starred review)
