Down and Out in Paris and London
'You can live on a shilling a day in Paris if you know how. But it is a complicated business'
As a struggling writer in his twenties, Orwell lived as a down-and-out among the poorest members of society. In this, his early memoir, Orwell recalls with vivid clarity his time working as a penniless dishwasher in Paris, pawning clothes to buy a day's worth of bread and wine, sleeping in bug-infested bunks, trading survival skills and cigarette butts with fellow tramps, and trudging between London's workhouse spikes for a few hours' sleep and tea.
With all of the sensitivity and compassion that Orwell is known and loved for, he exposed the hardships of poverty and gave readers an unprecedented look at life lived on the fringes of society.

The Ballad of Songbirds and Snakes
"Everything you would expect from Collins is
here: fraught teenage love; plenty of violence... the themes of
friendship, betrayal, authority and oppression will please and thrill"
The Guardian
"It works beautifully... please don't
make us wait another decade" The Times
Ambition will fuel him.
Competition
will drive him.
But power has its price.
It is the morning of the reaping that will kick off the tenth
annual Hunger Games. In the Capitol, eighteen-year-old Coriolanus
Snow is preparing for his one shot at glory as a mentor in the Games.
The once-mighty house of Snow has fallen on hard times, its
fate hanging on the slender chance that Coriolanus will be able
to outcharm, outwit, and outmaneuvre his fellow students to mentor
the winning tribute.
The odds are against him. He's been given the humiliating assignment
of mentoring the female tribute from District 12, the lowest
of the low. Their fates are now completely intertwined - ; every
choice Coriolanus makes could lead to favour or failure, triumph
or ruin. Inside the arena, it will be a fight to the death. Outside
the arena, Coriolanus starts to feel for his doomed tribute...
and must weigh his need to follow the rules against his desire
to survive no matter what it takes.

Keep Calm and Zomri
Tvárime sa ako drsňáci na internete, ale v skutočnosti sme rozmaznaní synáčikovia, ktorí sa dojmú pri každej somarine. Vytáčajú nás idioti, chrapúni a prakokoti. Bez nich by tu bolo lepšie, ale naše fungovanie by nedávalo zmysel. A to je paradoxne presne to, čo chceme dosiahnuť a čoho sa chceme dožiť. Aby tu raz bolo tak dobre, že by Zomri mohlo v pokoji zomrieť. Momentálne však Zomri žije možno viac, ako by sme si to všetci priali. A s vašou podporou ešte aj dlho bude.
Už takmer tri desiatky rokov existuje slovenská spoločnosť v nejakom zvláštnom medzisvete a nevie sa úplne rozhodnúť, kam chce patriť.
Ľudia boli od konca štyridsiatych rokov 20. storočia zvyknutí, že sa o nich stará niekto iný a že do vecí okolo seba vlastne nemajú ako zasiahnuť. Po prevrate prišiel prúser. Na jednej strane stáli nadšenci a idealisti, ktorí z tejto krajiny chceli urobiť modernú spoločnosť založenú na demokratických základoch, a na opačnej hajzli, ktorí svojimi demagógiami ťahajú ľudí do stredoveku. Tento boj dodnes nielen že pretrváva, je silnejší ako kedykoľvek predtým. Moc ovládajú populisti, v parlamente sedia nacisti. Demokratická opozícia je v absolútnom rozvrate, raz sa prikláňa na stranu populistov, inokedy slabučko hryzne.
V stave tohto marazmu vzniklo Zomri úplne spontánne. Pôvodne sme boli jednoduchá facebooková stránka, ktorá uverejňovala vtipy a upozorňovala na prešľapy.
Teraz sme však už miestom, kam sa ľudia chodia uvoľniť po dni naplnenom politikmi, ktorí dennodenne serú na hlavy celej verejnosti. Keď sa vám z paláca vládnej strany smejú do ksichtu a potom idú prespať k usvedčeným zločincom, keď občianske slobody označujú za ohrozenie štátu a kriminálka vyšetruje študentov organizujúcich protesty tak viete, že ste sa za tých tridsať rokov posunuli viac dozadu, ako dopredu.
My na to odpovede nemáme. Snažíme sa len tieto šialenstvá priniesť čo najširšej verejnosti v jazyku, ktorý máme všetci spoločný a zakorenený niekde v hlbinách našich duší. V jazyku humoru, dôvtipu a vulgarity.
Zomri je občianska sebaobrana.

Thinking Fast and Slow
Why is there more chance we'll believe something if it's in a bold type face? Why are judges more likely to deny parole before lunch? Why do we assume a good-looking person will be more competent? The answer lies in the two ways we make choices: fast, intuitive thinking, and slow, rational thinking. This book reveals how our minds are tripped up by error and prejudice (even when we think we are being logical), and gives you practical techniques for slower, smarter thinking. It will enable to you make better decisions at work, at home, and in everything you do.
Court of Wings and Ruin

MaasFeyre has returned to the Spring Court, determined to gather information on Tamlin's manoeuvrings and the invading king threatening to bring her land to its knees. But to do so she must play a deadly game of deceit - and one slip may spell doom not only for Feyre, but for her world as well.
As war bears down upon them all, Feyre must decide who to trust amongst the dazzling and lethal High Lords and hunt for allies in unexpected places. And her heart will face the ultimate test as she and her mate are forced to question whether they can truly trust each other. Sarah J.
Maas's books have sold more than nine million copies and been translated into 37 languages. Discover the sweeping romantic fantasy for yourself.
Nick and Charlie
A short novella based on the beloved characters from the graphic novel Heartstopper and Alice Oseman's debut novel Solitaire, which was praised as 'The Catcher in the Rye for the digital age' by The Times.
Absence makes the heart grow fonder, right?
CHARLIE: "I have been going out with Nick Nelson for two years. He likes rugby, Formula 1, dogs, the Marvel universe, the sound felt-tips make on paper, rain and drawing on shoes. He also likes me."
NICK: "Things me and Charlie Spring do together include: Watch films. Sit in the same room on different laptops. Text each other from different rooms. Make out. Make food. Make drinks. Get drunk. Talk. Argue. Laugh. Maybe we're kind of boring. But that's fine with us."
Everyone knows that Nick and Charlie are the perfect couple - that they're inseparable. But now Nick is leaving for university, and Charlie will be left behind at Sixth Form. Everyone's asking if they're staying together, which is a stupid question - they're 'Nick and Charlie' for God's sake!
But as the time to say goodbye gets inevitably closer, both Nick and Charlie question whether their love is strong enough to survive being apart. Or are they delaying the inevitable? Because everyone knows that first loves rarely last forever...
