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).

Book excerpt: To protect those who matter most, we will betray others in ways we never expected. This is supposed to be a good year. With a new set of instructors - and ones I know well - I'm sure it will be. For once, things are finally starting to go my way. My mentors are proud, my family is closer than ever before, and I am happy. Unfortunately, the gods are tired of waiting. Every day, Zeal grows stronger, but Ambition, Inspiration, Perception, Compassion, and Intuition don't. They're fading, with no hope in sight. Except me. Piece by piece, my god has built me up, given me "weapons" to use, and made me into the kind of woman I can be proud of. He calls me his partner and that isn't an empty title. It means more than just serving him. I can tell by the longing in his divine eyes. My success doesn't go unnoticed, though. My haters want to destroy me, but let them try. Petty bullying is too childish for me to worry about. With so many priests able to see the God of Temptation now, I no longer care who likes me and who doesn't. And that's my biggest mistake. Because my god doesn't run this temple. He doesn't make the rules. With a single signed paper, I'm no longer as safe as I thought. Friends are going to be betrayed. Lovers will suffer. Somehow, I have to fix this. I am the Priestess of Temptation, Zeal's chosen. Someone is going to be punished. I almost hope it's me. Possible Triggers: Discussions of rape and assault, domestic violence, bullying, harassment, consensual pain and battery, shaming, sexual sadism, minor violence, and more adult themes. The Path of Temptation series features a strong woman and the men who love her. Graphic language, adult situations, and potentially triggering violence that are suitable for a mature audience are included. This is a love story, but sometimes love comes with a price.
