New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.

Gus never imagined himself a parent at thirteen. But in the war-fraught summer of 1942, while living on his grandparents' Vermont farm, he adopts a clutch of orphaned duck eggs. Gus can relate to the foundlings, as he is apart from, and yearns for, his own family. One day Gus finds a young stranger standing over the incubating eggs. Gus doesn't know what to make of her, with her tattered clothing and strange accent, but soon the girl is helping to care for the newly hatched ducklings, and she and Gus become fast friends. Not everyone shares Gus's high opinion of Louise, whose poverty-stricken French-Canadian family is shunned by the townspeople. His attempt to help his friend and her family has some embarrassing consequences and he must make retribution if he is to keep Louise's friendship. Nancy Price Graff's fluid narrative and exceptional eye for detail follow Gus during a time of food rationing, Victory gardens, watching for enemy planes--and keeping his ducks from harm.

Ages ago, sorcerers of unmatched power sundered a world into four realms—sky, stone, fire, and water—then vanished. Over time, magicians learned to work spells only in their own realms and forgot the others. Now only the few who have survived the Labyrinth and crossed the Death Gate know of the presence of all four realms—and even they have yet to unravel the mysteries of their severed world. . . . In Arianus, Realm of Sky, humans, elves, and dwarves battle for control of precious water—traversing a world of airborne islands on currents of elven magic and the backs of mammoth dragons. But soon great magical forces will begin to rend the fabric of this delicate land. An assassin will be hired to kill a royal prince—by the king himself. A dwarf will challenge the beliefs of his people—and lead them in rebellion. And a sinister wizard will enact his plan to rule Arianus—a plan that may be felt far beyond the Realm of Sky and into the Death Gate itself.

“In Surgical Wing, you will find yourself in phone booths, county fairs, fishing boats, and among ghosts. Strange birds will enter hospital waiting rooms. You will be seduced by knot-makers. You will witness illness, grief, and healing. Finally, the book itself will become the wings that steer you to a greater understanding of yourself and the world.” —Anna Silver In Surgical Wing, surrealistic poems visit an experimental hospital ward, manifesting visions of winged angels and medical tests, as we bear witness to a doctor’s’ meddling and miracles. Robertson’s poems challenge the internal and external metamorphoses of the human condition and the juxtaposition between death and life by personifying the soul through images of birds. From “You’re About to Fold a Paper Airplane”: Build evidence of air. Pull the results of your blood test from the mailbox. Fold in half: you have wings already. Abnormal? Fold again. You can’t see the inner-workings of an aircraft. And when you’re folding, you can’t study much else. Book your tumor markers a flight to Bora Bora. Vector, Victor. Clearance, Clarence. On any scrap of paper write carry. Write heavenward. Write I choose this over you. Replace this. With flying. With peregrination. Or write I can’t fear you another morning. And fold. Kristin Robertson is a native of East Tennessee, and she graduated with a PhD in creative writing from Georgia State University in Atlanta. Her poetry has appeared or is forthcoming in Harvard Review, Indiana Review, TriQuarterly, Third Coast, and Verse Daily, among other journals. Kristin lives outside Los Angeles and teaches at the University of California, Riverside.

“Such a visual piece . . . readers young and old will return to the story to look more deeply; they won’t be disappointed.” — Booklist (starred review) In a city full of hurried people, only young Will notices the bird lying hurt on the ground. With the help of his sympathetic mother, he gently wraps the injured bird and takes it home. Wistful and uplifting in true Bob Graham fashion, here is a tale of possibility — and of the souls who never doubt its power.

Jandy Nelson meets Friday Night Lights in this sweeping, warm, arrestingly original novel about family, poverty, and hope. Wing Jones, like everyone else in her town, has worshipped her older brother, Marcus, for as long as she can remember. Good-looking, popular, and the star of the football team, Marcus is everything his sister is not. Until the night everything changes when Marcus, drunk at the wheel after a party, kills two people and barely survives himself. With Marcus now in a coma, Wing is crushed, confused, and angry. She is tormented at school for Marcus’s mistake, haunted at home by her mother and grandmothers’ grief. In addition to all this, Wing is scared that the bank is going to repossess her home because her family can’t afford Marcus’s mounting medical bills. Every night, unable to sleep, Wing finds herself sneaking out to go to the school’s empty track. When Aaron, Marcus’s best friend, sees her running one night, he recognizes that her speed, skill, and agility could get her spot on the track team. And better still, an opportunity at a coveted sponsorship from a major athletic gear company. Wing can’t pass up the opportunity to train with her longtime crush and to help her struggling family, but can she handle being thrust out of Marcus’s shadow and into the spotlight? "The swiftly paced story will quickly sweep up readers...[a] well-crafted, inspirational debut with plenty of heart, hope, and determination." —Booklist "A story showing how hope and love can blossom in the midst of chaos." —Publishers Weekly
