In her own singularly beautiful style, Newbery Medal winner Sharon Creech intricately weaves together two tales, one funny, one bittersweet, to create a heartwarming, compelling, and utterly moving story of love, loss, and the complexity of human emotion. Thirteen-year-old Salamanca Tree Hiddle, proud of her country roots and the "Indian-ness in her blood," travels from Ohio to Idaho with her eccentric grandparents. Along the way, she tells them of the story of Phoebe Winterbottom, who received mysterious messages, who met a "potential lunatic," and whose mother disappeared. As Sal entertains her grandparents with Phoebe's outrageous story, her own story begins to unfold—the story of a thirteen-year-old girl whose only wish is to be reunited with her missing mother.

Previously published by Del Rey Books as two separate novels--"Inherit the Stars" and "The Gentle Giants of Ganymede"--these two stories, now available in one volume, began Hogan's legendary Giants series and the career of a major SF talent.

Astronomy, politics, and romance join forces in this novel from the writer John Updike has called "one of the most interesting American novelists at work." It's the spring of 1877 in Washington, D.C., and at the U.S. Naval Observatory, Hugh Allison has conceived a secret ambition: to project an image through time and space. But his plan takes on urgent life only when the mathematically gifted Cynthia May enters his orbit as one of the observatory's human "computers." A Civil War widow whose beauty has been shadowed by worry and poverty, Cynthia reluctantly falls in love with the younger Hugh, who missed the war that has haunted her life. But the fate of their love affair -- and of Hugh's heavenly vision -- may be out of their hands, decided instead by an astrologer and by the actions of a dangerously magnetic politician who wields his power over a Senate convulsed by Reconstruction and a wildly disputed presidential election. Masterfully combining historical detail and startling invention, Thomas Mallon gives us a galvanizing story of earthly heartbreak and otherworldly triumph.

An astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists. In 1959, the Soviet probe Luna 3 took the first photos of the far side of the moon. Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon. In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here—and billions of miles from home.

"What if?" questions stimulate people to think in new ways, to refresh old ideas, and to make new discoveries. In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring. This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult alike, this book is a fascinating journey through physics and astronomy, and follows on the author's previous bestseller, What if the Moon Didn't Exist?, with completely new scenarios backed by the latest astronomical research.

When their teacher goes missing during an outing, eleven girls grapple with the aftermath in this haunting, exquisitely told psychological mystery. The Vietnam War rages overseas, but back at home, in a year that begins with the hanging of one man and ends with the drowning of another, eleven schoolgirls embrace their own chilling history when their teacher abruptly goes missing on a field trip. Who was the mysterious poet they had met in the Garden? What actually happened in the seaside cave that day? And most important — who can they tell about it? In beautifully shimmering prose, Ursula Dubosarsky reveals how a single shared experience can alter the course of young lives forever. Part gripping thriller, part ethereal tale of innocence lost, The Golden Day is a poignant study of fear and friendship, and of what it takes to come of age with courage.
