Letters to a Young Contrarian

In the book that he was born to write, provocateur and best-selling author Christopher Hitchens inspires future generations of radicals, gadflies, mavericks, rebels, angry young (wo)men, and dissidents. Who better to speak to that person who finds him or herself in a contrarian position than Hitchens, who has made a career of disagreeing in profound and entertaining ways.This book explores the entire range of “contrary positions”-from noble dissident to gratuitous pain in the butt. In an age of overly polite debate bending over backward to reach a happy consensus within an increasingly centrist political dialogue, Hitchens pointedly pitches himself in contrast. He bemoans the loss of the skills of dialectical thinking evident in contemporary society. He understands the importance of disagreement-to personal integrity, to informed discussion, to true progress-heck, to democracy itself. Epigrammatic, spunky, witty, in your face, timeless and timely, this book is everything you would expect from a mentoring contrarian.

The Letters of J. R. R.Tolkien

‘…If you wanted to go on from the end of The Hobbit I think the ring would be your inevitable choice as the link. If then you wanted a large tale, the Ring would at once acquire a capital letter; and the Dark Lord would immediately appear. As he did, unasked, on the hearth at Bag End as soon as I came to that point. So the essential Quest started at once. But I met a lot of things along the way that astonished me. Tom Bombadil I knew already; but I had never been to Bree. Strider sitting in the corner of the inn was a shock, and I had no more idea who he was than Frodo did. The Mines of Moria had been a mere name; and of Lothlorien no word had reached my mortal ears till I came there.’ — J.R.R. Tolkien to W.H. Auden, June 7, 1955

J.R.R. Tolkien, cherished author of The Hobbit, The Lord of the Rings, and The Silmarillion, was one of the twentieth century’s most prolific letter writers. Over the years he wrote a mass of letters — to his publishers, his family, to friends, and to fans of his books — which record the history and composition of his works and his reaction to subsequent events.

By turns thoughtful, impish, scholarly, impassioned, playful, vigorous, and gentle, Tolkien poured his heart and mind into a great stream of correspondence to intimate friends and unknown admirers all over the world. From this collection one sees a mind of immense complexity and many layers — artistic, religious, charmingly eccentric, sentimental, and ultimately brilliant.

Now newly expanded with a detailed index, this collection provides an invaluable record that sheds much light on Tolkien’s creative genius, his thoughts and feelings about his own work, and the evolution of his grand design for the creation of a whole new world — Middle-earth.

When Billy, a troubled young man, comes to private eye Cormoran Strike’s office to ask for his help investigating a crime he thinks he witnessed as a child, Strike is left deeply unsettled. While Billy is obviously mentally distressed, and cannot remember many concrete details, there is something sincere about him and his story. But before Strike can question him further, Billy bolts from his office in a panic.
Trying to get to the bottom of Billy’s story, Strike and Robin Ellacott – once his assistant, now a partner in the agency – set off on a twisting trail that leads them through the backstreets of London, into a secretive inner sanctum within Parliament, and to a beautiful but sinister manor house deep in the countryside.
And during this labyrinthine investigation, Strike’s own life is far from straightforward: his newfound fame as a private eye means he can no longer operate behind the scenes as he once did. Plus, his relationship with his former assistant is more fraught than it ever has been – Robin is now invaluable to Strike in the business, but their personal relationship is much, much more tricky than that . . .
**The most epic Robert Galbraith novel yet, LETHAL WHITE is both a gripping mystery and a page-turning next instalment in the ongoing story of Cormoran Strike and Robin Ellacott.**

Lethal Experiment

What if someone offered you $100,000 with the only stipulation being that a murderer would be killed if you accept the money? Would you take it? The people who choose to take it are about to find out the ramifications of their decisions to be part of this Lethal Experiment!

In this sequel to Lethal People, Creed is forced to choose between his thriving contract-killer business, his part in the Lethal Experiment, and his desire to live a normal life with the beautiful Kathleen Gray and her newly-adopted daughter, Addie. Before that can happen, he has to take care of some lethal business involving a former lover.
*Lethal Experiment* is a breezy and fun page-turner, featuring grisly humor, outrageous characters, and sexy dialogue.

Let’s All Kill Constance

One of Ray Bradbury’s classic novels, available in ebook for the first time. On a dismal evening in the previous century, an unnamed writer in Venice, California, answers a furious pounding at his beachfront bungalow door and again admits Constance Rattigan into his life. An aging, once-glamorous Hollywood star, Constance is running in fear from something she dares not acknowledge – and vanishes as suddenly as she appeared, leaving the narrator two macabre books: twin listings of the Tinseltown dead and soon to be dead, with Constance’s name included among them. And so begins an odyssey as dark as it is wondrous, as the writer sets off in a broken-down jalopy with his irascible sidekick Crumley to sift through the ashes of a bygone Hollywood – a graveyard of ghosts and secrets where each twisted road leads to grim shrines and shattered dreams … and, all too often, to death.

The ghosts of the past will shape your future. Unless you fight them.
*Cambridge Fellows Mysteries, Book 4*
Cambridge, 1907
After settling in their new home, Cambridge dons Orlando Coppersmith and Jonty Stewart are looking forward to nothing more exciting than teaching their students and playing rugby. Their plans change when a friend asks their help to clear an old flame who stands accused of murder.
Doing the right thing means Jonty and Orlando must leave the sheltering walls of St. Bride’s to enter a labyrinth of suspects and suspicions, lies and anguish.
Their investigation raises ghosts from Jonty’s past when the murder victim turns out to be one of the men who sexually abused him at school. The trauma forces Jonty to withdraw behind a wall of painful memories. And Orlando fears he may forever lose the intimacy of his best friend and lover.
When another one of Jonty’s abusers is found dead, police suspicion falls on the Cambridge fellows themselves. Finding this murderer becomes a race to solve the crime… before it destroys Jonty’s fragile state of mind.
*Warning: Contains sensual m/m lovemaking and hot men playing rugby.*

Learning the Ropes

Working for a company whose slogan is ‘Sex sells and we’re very good at sex’ isn’t easy for a man with an apparently inexhaustible ability to blush. Things only get more embarrassing for Floyd when he’s sent to construct an advertising campaign for a BDSM club.
As if that wasn’t bad enough, the owner of the club is Peter Ingram, the silent partner in SKIN designs, which technically makes him Floyd’s boss. If he screws this up, Floyd’s going to be looking for a new job. His only option is to set aside his embarrassment and throw himself into learning everything there is to know about leather.
But when Peter agrees to teach Floyd what submission really means, suddenly it’s not only his job that’s at risk.
