The Five People You Meet in Heaven by
Eddie is a wounded war veteran, an old man who has lived, in his mind, an uninspired life. His job is fixing rides at a seaside amusement park. On his 83rd birthday, a tragic accident kills him as he tries to save a little girl from a falling cart. He awakes in the afterlife, where he learns that heaven is not a destination, but an answer.
In heaven, five people explain your life to you. Some you knew, others may have been strangers. One by one, from childhood to soldier to old age, Eddie's five people revisit their connections to him on earth, illuminating the mysteries of his "meaningless" life, and revealing the haunting secret behind the eternal question: "Why was I here?"

The God of Small Things by
Compared favorably to the works of Faulkner and Dickens, Arundhati Roy’s debut novel is a modern classic that has been read and loved worldwide. Equal parts powerful family saga, forbidden love story, and piercing political drama, it is the story of an affluent Indian family forever changed by one fateful day in 1969. The seven-year-old twins Estha and Rahel see their world shaken irrevokably by the arrival of their beautiful young cousin, Sophie. It is an event that will lead to an illicit liaison and tragedies accidental and intentional, exposing “big things [that] lurk unsaid” in a country drifting dangerously toward unrest. Lush, lyrical, and unnerving, The God of Small Things is an award-winning landmark that started for its author an esteemed career of fiction and political commentary that continues unabated.

Life of Pi by
Winner of the 2002 Man Booker Prize for Fiction Pi Patel is an unusual boy. The son of a zookeeper, he has an encyclopedic knowledge of animal behavior, a fervent love of stories, and practices not only his native Hinduism, but also Christianity and Islam. When Pi is sixteen, his family emigrates from India to North America aboard a Japanese cargo ship, along with their zoo animals bound for new homes. The ship sinks. Pi finds himself alone in a lifeboat, his only companions a hyena, an orangutan, a wounded zebra, and Richard Parker, a 450-pound Bengal tiger. Soon the tiger has dispatched all but Pi, whose fear, knowledge, and cunning allow him to coexist with Richard Parker for 227 days lost at sea. When they finally reach the coast of Mexico, Richard Parker flees to the jungle, never to be seen again. The Japanese authorities who interrogate Pi refuse to believe his story and press him to tell them "the truth." After hours of coercion, Pi tells a second story, a story much less fantastical, much more conventional-but is it more true? Life of Pi is at once a realistic, rousing adventure and a meta-tale of survival that explores the redemptive power of storytelling and the transformative nature of fiction. It's a story, as one character puts it, to make you believe in God.

How to be both by
Passionate, compassionate, vitally inventive and scrupulously playful, Ali Smith’s novels are like nothing else. Borrowing from painting’s fresco technique to make an original literary double-take, How to be both is a novel all about art’s versatility. It’s a fast-moving genre-bending conversation between forms, times, truths and fictions. There’s a Renaissance artist of the 1460s. There’s the child of a child of the 1960s. Two tales of love and injustice twist into a singular yarn where time gets timeless, structural gets playful, knowing gets mysterious, fictional gets real—and all life’s givens get given a second chance.
