Lucky Leonardo

Leonardo Cook, practicing psychiatrist, is experiencing a delicate emotional phase. His wife has left him for another man, his patients are boring and he's feeling somewhat guilty about his relationship with his girlfriend, a Starbucks employee half his age. And he may be on the verge of another nervous breakdown. When Leonardo is called upon by a friend to talk a tech genius out of making public a secret new innovation-and the tech genius ends up jumping out of the window-Leonardo's life takes flight on a roller-coaster of disaster. Making a darkly hilarious debut, Jonathan Canter gleefully builds a small Massachusetts town filled with the interrelated lives of fantastically neurotic characters-and at their center, poor, "lucky" Leonardo. Fast-paced and laugh-out-loud funny, Lucky Leonardo is not to be missed.

Leonardo’s Science Workshop leads children on an interactive adventure through key science concepts by following the multidisciplinary approach of the Renaissance period polymath Leonardo da Vinci: experimenting, creating projects, and exploring how art intersects with science and nature. Photos of Leonardo’s own notebooks, paintings, and drawings provide visual inspiration. More than 500 years ago, Leonardo knew that the fields of science, technology, engineering, art, and mathematics (STEAM) are all connected. The insatiably curious Leonardo examined not just the outer appearance of his art subjects, but the science that explained them. He began his studies as a painter, but his curiosity, diligence, and genius made him also a master sculptor, architect, designer, scientist, engineer, and inventor. The Leonardo’s Workshop series shares this spirit of multidisciplinary inquiry with children through accessible, engaging explanations and hands-on learning. This fascinating book harnesses children’s innate curiosity to explore some of Leonardo’s favorite subjects, including flight, motion, technology design, perspective, and astronomy. After each topic is explained with concepts from physics, chemistry, math, and engineering, kids can experience the principles first-hand with step-by-step STEAM projects. They will explore: The physics of flight by observing birds and experimenting with paper airplane designs The science of motion by building a windup dragonfly Gravitational acceleration with water balloons The movement of electrons by making cereal “dance” Technology design by making paper and fabric using recycled material Scientific perspective by drawing a 3D illusion Insight from other great thinkers—such as Galileo Galilei, James Clerk Maxwell, and Sir Isaac Newton—are woven into the lessons throughout. Introduce vital STEAM skills through visually rich, hands-on learning with Leonardo’s Science Workshop.

Leonardo is only in his early twenties and doesn't expect much from life. His father became an alcoholic after his mother died, and now Leonardo has to work two jobs to pay the family bills, as well as some of his father's debts in nightclubs. He's tired of this life, full of hard work to get his father out of trouble, which has cost him four jobs. Leonardo went home tired and, as soon as he opened the door, he was shocked to find three other men in the room, in addition to his injured father, one of them pointing a gun at his father's head. The man turned his head to look at him coldly, examining him from head to toe. Leonardo only felt chills down his spine. "Your dear father owes me some money. I gave him a deadline, but he didn't meet it, and I came to collect the debt." "How much?" "Twenty-eight thousand dollars." "What?" He was later cornered by Frank Gold, the mobster, who seemed to want something more than money...

Featuring a brand new introduction from bestselling author, Carmel Harrington, talking about what Jackie and her books mean to her! ‘Lessons galore on every page… about feminism, equality, tolerance and love’ CARMEL HARRINGTON 'Jackie Collins’s daring, unapologetic stroke of the pen, combined with her glorious wit, has single-handedly given creative license to new generations of authors and storytellers.' COLLEEN HOOVER Dangerous Kiss is a story of raw anger, love, lust, murder and revenge, and at its white-hot center is Lucky Santangelo, a strong, exciting woman who dares to take chances – and always wins. There have been many imitators, but only ever one Jackie Collins. With millions of her books sold around the world, and thirty-one New York Times bestsellers, she is one of the world’s top-selling novelists. From glamorous Beverly Hills bedrooms to Hollywood movie studios; from glittering rock concerts to the yachts of billionaires, Jackie chronicled the scandalous lives of the rich, famous, and infamous from the inside looking out. 'A true inspiration, a trail blazer for women's fiction' JILLY COOPER ‘Jackie shows us all what being a strong, successful woman means at any age’ MILLY JOHNSON ‘Jackie will never be forgotten, she’ll always inspire me to #BeMoreJackie’ JILL MANSELL ‘Jackie’s heroines don’t take off their clothes to please a man, but to please themselves’ CLARE MACKINTOSH ‘Legend is a word used too lightly for so many undeserving people, but Jackie is the very definition of the word’ ALEX KHAN ‘What Jackie knew how to do so well, is to tell a thumping good story’ ROWAN COLEMAN ‘I read hundreds of books every year. But Jackie Collins’ novels are the only ones I can read over and over’ AMY ROWLAND ‘Jackie wrote with shameless ambition, ruthless passion and pure diamond-dusted sparkle’ CATHERINE STEADMAN ‘Here is a woman who not only wanted to entertain her readers, but also to teach them something; about the world and about themselves’ ISABELLE BROOM ‘There’s a lot a drag queen can learn from Jackie’ TOM RASMUSSEN ‘Jackie is the queen of cliff-hangers’ SAMANTHA TONGE ‘For all her trademark sass, there is a moralist at work here’ LOUISE CANDLISH ‘Nobody does it quite like Jackie and nobody ever will’ SARRA MANNING ‘Jackie bought a bit of glitter, sparkle and sunshine into our humdrum existence’ VERONICA HENRY ‘What radiates from her novels, is a sense that women are capable of great things’ ALEXANDRA HEMINSLEY

BAPTISM OF FIRE is a turbulent family drama and highly charged love story set in Cuba in 1956-1960 against the backdrop of Fidel Castro's revolution.

In 1987 a young Jewish man, the central figure in this captivating book, leaves Moscow for good with his parents. They celebrate their freedom in opulent Vienna and spend two months in Rome and the coastal resort of Ladispoli. While waiting in Europe for a U.S. refugee visa, the book’s twenty-year-old poet quenches his thirst for sexual and cultural discovery. Through his colorful Austrian and Italian misadventures, he experiences the shock, thrill, and anonymity of encountering Western democracies, running into European roadblocks while shedding Soviet social taboos. As he anticipates entering a new life in America, he movingly describes the baggage that exiles bring with them, from the inescapable family traps and ties to the sweet cargo of memory. An emigration story, Waiting for America explores the rapid expansion of identity at the cusp of a new, American life. Told in a revelatory first-person narrative, Waiting for America is also a vibrant love story in which the romantic main character is torn between Russian and Western women. Filled with poignant humor and reinforced by hope and idealism, the author’s confessional voice carries the reader in the same way one is carried through literary memoirs like Tolstoy’s Childhood, Boyhood, Youth, Hemingway’s A Moveable Feast, or Nabokov’s Speak, Memory. Babel, Sebald, and Singer—all transcultural masters of identity writing—are the coordinates that help to locate Waiting for America on the greater map of literature.
