Download or read book Lila and Hadley written by Kody Keplinger and published by Scholastic Inc.. This book was released on 2020-04-07 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can a lost girl save a found dog? Find out in this unforgettable story about discovering true friendship, finding home, and the possibilities of forgiveness. Hadley is angry about a lot of things: Her mom going to jail. Having to move to another state to live with her older sister, Beth, even though they haven't spoken in five years. Leaving her friends and her school behind. And going blind. But then Hadley meets Lila. Lila is an abandoned dog who spends her days just quietly lying around at the local dog rescue where Beth works. She doesn't listen to directions or play with the other dogs or show any interest in people. So when Lila comes and sits by Hadley (which is hardly anything, but it's more than she's done with others), Beth thinks maybe Hadley can help Lila. She tells Hadley they'll bring Lila home as a foster dog and Hadley can teach her to follow commands, walk on a leash, and be more of a people dog so she's ready to be adopted. Only working with Lila is harder than Hadley thought, and so is the mobility training she starts taking to help with her failing vision. It feels like Lila is too stubborn to train and that learning to use a cane is impossible. But unless Hadley can help Lila, she'll never be adopted into a home. If Hadley could just let go of her anger, she might be able to save Lila ... and herself. New York Times bestselling author Kody Keplinger weaves an unforgettable story about discovering true friendship, finding home, and the possibilities of forgiveness.

Book excerpt: “With each new book by Tessa Hadley, I grow more convinced that she’s one of the greatest stylists alive.”—Ron Charles, Washington Post New York Times Book Review Editors' Choice |A Parnassus First Editions Club Pick | Powell’s Indispensable Book Club Pick | A Washington Post Notable Book | A Slate Best Book of the Year | A Boston Globe Best Book of the Year | A Bookpage Best Book of the Year The lives of two close-knit couples are irrevocably changed by an untimely death in the latest from Tessa Hadley, the acclaimed novelist and short story master who “recruits admirers with each book” (Hilary Mantel). Alexandr and Christine and Zachary and Lydia have been friends since they first met in their twenties. Thirty years later, Alex and Christine are spending a leisurely summer’s evening at home when they receive a call from a distraught Lydia: she is at the hospital. Zach is dead. In the wake of this profound loss, the three friends find themselves unmoored; all agree that Zach, with his generous, grounded spirit, was the irreplaceable one they couldn’t afford to lose. Inconsolable, Lydia moves in with Alex and Christine. But instead of loss bringing them closer, the three of them find over the following months that it warps their relationships, as old entanglements and grievances rise from the past, and love and sorrow give way to anger and bitterness. Late in the Day explores the complex webs at the center of our most intimate relationships, to expose how, beneath the seemingly dependable arrangements we make for our lives, lie infinite alternate configurations. Ingeniously moving between past and present and through the intricacies of her characters’ thoughts and interactions, Tessa Hadley once again “crystallizes the atmosphere of ordinary life in prose somehow miraculous and natural” (Washington Post).

Download or read book Power of Lies written by Auryn Hadley and published by . This book was released on 2019-01-15 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everyone lies. When working for a sex mage, it's the only way to stay safe. That's the first thing Jaeda learns when she's named as the Chosen. The mage needs a sacrifice, and she's willing to give it. Maybe too willing. After all, this man is lust incarnate; a woman would have to be insane not to want him, even if he is dangerous. But desiring someone's body is very different from falling in love. In her line of work, the two must never be confused. She doesn't even know his name! He's simply The Jackal, a terrifyingly powerful sex mage, and she's his altar. Her lust fuels him. He needs it. And that puts her in control. Now, she gets to spend her days with a mage who wields sex like a weapon and his assistant who's as irresistible as some long-lost god brought to life. The things they do to her body are amazing, and the rest? These men want to spoil her with the kind of riches she's always dreamed of. It's the best job she can imagine. Unfortunately, it's never that easy. This is supposed to be about making magic - that's it. Feelings have no place in a mage's temple. Affection is a curse. But when the enemy decides she'll make the perfect weapon to steal the Jackal's power, what's she supposed to do? After all, she's just a stupid girl caught in the middle. Her job is to just lie back and take it. Except, someone's been lying. It might even be her. POWER OF LIES is a complete novel with a reverse harem, polyamorous storyline. It is intended for a mature audience due to the presence of consensual sex, group sex, M/M scenes, and plenty of vulgar language - as well as some potentially triggering violence since the bad guys don't always play nice. While this is a love story, it may not be right for all readers.

Download or read book First Things written by Hadley Arkes and published by Princeton University Press. This book was released on 2020-06-16 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book restores to us an understanding that was once settled in the "moral sciences": that there are propositions, in morals and law, which are not only true but which cannot be otherwise. It was understood in the past that, in morals or in mathematics, our knowledge begins with certain axioms that must hold true of necessity; that the principles drawn from these axioms hold true universally, unaffected by variations in local "cultures"; and that the presence of these axioms makes it possible to have, in the domain of morals, some right answers. Hadley Arkes restates the grounds of that older understanding and unfolds its implications for the most vexing political problems of our day. The author turns first to the classic debate between Abraham Lincoln and Stephen Douglas. After establishing the groundwork and properties of moral propositions, he traces their application in such issues as selective conscientious objection, justifications for war, the war in Vietnam, a nation's obligation to intervene abroad, the notion of supererogatory acts, the claims of "privacy," and the problem of abortion.

Book excerpt: In this New York Times Notable Book from one of today’s most acclaimed writers, two lives stretched between two cities converge in a chance meeting that will irrevocably change their lives. “Hadley is a supremely perceptive writer of formidable skill and intelligence, someone who goes well beyond surfaces.”—New York Times Book Review Unsettled by the recent death of his mother, Paul sets out in search of Pia, his daughter from his first marriage, who has disappeared into the labyrinth of London. Discovering her pregnant and living illegally in a run-down council flat with a pair of Polish siblings, Paul is entranced by Pia’s excitement at living on the edge. Abandoning his second wife and their children in Wales, he joins her to begin a new life in the heart of London. Cora, meanwhile, is running in the opposite direction, back to Cardiff, to the house she has inherited from her parents. She is escaping her marriage, and the constrictions and disappointments of her life in London. But there is a deeper reason why she cannot stay with her decent Civil Service husband; the aftershocks of which she hasn’t fully come to terms with herself. Connecting both stories is the London train, and a chance meeting that will have immediate and far-reaching consequences for both Paul and Cora.
