It is the early 1980s, and America is in love with space. Growing up in the shadow of Cape Canaveral, young Dolores Gray has it particularly bad: she dreams of becoming an astronaut. At school, Dolores finds herself caught between her desire for popularity and her secret friendship with the smartest and most unpopular boy in her class, whose father is NASA's Director of Launch Safety. At home, discord begins to grow between her parents when her father's job as a NASA technician is threatened. Looking for escape, Dolores loses herself in her scrapbook, where she files away newspaper articles about the astronauts and the shuttles, weather reports on launch scrubs, and stories about her idol, Judith Resnik. Then, on the morning of January 28, 1986, seventy-three seconds after liftoff, the space shuttle Challenger explodes, killing all seven astronauts on board -- including Judith Resnik. It is a moment that shakes America to its core, and nowhere is it more deeply felt than in central Florida. Dolores becomes determined to reconstruct what went wrong, both in her parent's marriage and at NASA, in the hope that she can save her father's job and keep her family together. The Time It Takes to Fall is a coming-of-age novel that deftly weaves the story of one family's drama into the larger picture of a touchstone event in American history. It is at once an intimate look at a young girl's loss of innocence and a portrait of America's loss of innocence -- the end of an era that romanticized manned space flight and would never be the same again.

Twenty-four years old and newly employed in Manhattan, Jenna McCann agrees to place herself under the dead body of a wealthy, prominent New Yorker—her boss—to hide the identity of his real lover. But why? Because she is half in love with him herself; because her only friend at Hull Industries asked her to; because she feared everyone around her; because she had no idea how this would spin out into her own, undeveloped life; because she had nothing and no one? Or just because? Deftly told and sharply observed, Jenna Takes the Fall is the story of someone who became infamous . . . before she became anybody at all.

Twin Peaks meets Thirteen Reasons Why in this gripping and evocative tale of one girl unraveling the mystery of her best friend's murder, from acclaimed author Emily Hainsworth. WHO KILLED GRETCHEN MEYER? Fear grips the residents of Hidden Falls the night Sonia Feldman and her best friend, Gretchen Meyer, are attacked in the woods. Sonia was lucky to escape with her life, but Gretchen's body is discovered at the bottom of a waterfall. Beautiful, popular, and seemingly untouchable, Gretchen can't be gone. Even as Sonia struggles with guilt and confusion over having survived, the whole town is looking to her for information. . . . Could she have seen something that will lead the police to the killer? At the top of the list of suspects is Gretchen's ex-boyfriend—and Sonia's longtime enemy—Marcus Perez. So when Marcus comes to Sonia for help clearing his name, she agrees, hoping to find evidence the police need to prove he's the killer. But as Gretchen's many secrets emerge and the suspects add up, Sonia feels less sure of Marcus's involvement and more afraid for herself. Could Marcus—the artist, the screw-up, the boy she might be falling for—have attacked her? Killed her best friend? And if it wasn't him in the woods that night . . . who could it have been?

Black & white print. University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Volume 1 covers mechanics, sound, oscillations, and waves. Volume 2 covers thermodynamics, electricity, and magnetism. Volume 3 covers optics and modern physics. This textbook emphasizes connections between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result.

An engaging collection of intriguing problems that shows you how to think like a mathematical physicist Paul Nahin is a master at explaining odd phenomena through straightforward mathematics. In this collection of twenty-six intriguing problems, he explores how mathematical physicists think. Always entertaining, the problems range from ancient catapult conundrums to the puzzling physics of a very peculiar material called NASTYGLASS—and from dodging trucks to why raindrops fall slower than the rate of gravity. The questions raised may seem impossible to answer at first and may require an unexpected twist in reasoning, but sometimes their solutions are surprisingly simple. Nahin’s goal, however, is always to guide readers—who will need only to have studied advanced high school math and physics—in expanding their mathematical thinking to make sense of the curiosities of the physical world. The problems are in the first part of the book and the solutions are in the second, so that readers may challenge themselves to solve the questions on their own before looking at the explanations. The problems show how mathematics—including algebra, trigonometry, geometry, and calculus—can be united with physical laws to solve both real and theoretical problems. Historical anecdotes woven throughout the book bring alive the circumstances and people involved in some amazing discoveries and achievements. More than a puzzle book, this work will immerse you in the delights of scientific history while honing your math skills.

"The perfect feel-good read."—Emily Henry, #1 New York Times bestselling author of People We Meet on Vacation Britta didn’t plan on falling for her personal trainer, and Wes didn’t plan on Britta. Plans change and it's unclear if love, career, or both will meet them at the finish line. Britta Colby works for a lifestyle website, and when tasked to write about her experience with a hot new body-positive fitness app that includes personal coaching, she knows it's a major opportunity to prove she should write for the site full-time. As CEO of the FitMi Fitness app, Wes Lawson finally has the financial security he grew up without, but despite his success, his floundering love life and complicated family situation leaves him feeling isolated and unfulfilled. He decides to get back to what he loves—coaching. Britta’s his first new client and they click immediately. As weeks pass, she’s surprised at how much she enjoys experimenting with her exercise routine. He’s surprised at how much he looks forward to talking to her every day. They convince themselves their attraction is harmless, but when they start working out in person, Wes and Britta find it increasingly challenging to deny their chemistry and maintain a professional distance. Wes isn’t supposed to be training clients, much less meeting with them, and Britta’s credibility will be sunk if the lifestyle site finds out she’s practically dating the fitness coach she’s reviewing. Walking away from each other is the smartest thing to do, but running side by side feels like the start of something big.
