I recommend Snow Crash. :)

I am no fantasy or sci-fi aficionado (more like a casual) but I want to recommend Tim Powers' On Stranger Tides. A friend told me about it a couple of years ago, but for some reason I always put off reading it until last month - and boy, is that book a blast. (I don't want to spoil anything about it but I would say it sort of fits in the wider fantasy category)

Horror is my favourite genre, and off the top of my head I suggest you check out a manga called Uzumaki. Really creepy and not too long. (it was also adapted into a movie, but I wasn't impressed)

I would recommend those novels by Tom Clancy, like The Hunt for Red October and Red Storm Rising.

I would recommend:

1. I Am a Hero
2. 1984
3. Dune
4. Children of Time
5. We Are Legion We Are Bob

The first two books I loved and thought of that might fall into your interests are:
ZERO ECHO SHADOW PRIME: An interesting sci-fi novel by Peter Samet that tackles the question of what makes us human. We have 4 main characters which are different versions of the same woman: Zero, the original suffering from cancer. Echo, a four armed clone on Planet Echo (basically a battle royale monster wasteland). Shadow, a holographic assistant. And Prime, a robot given perhaps too much humanity in her programming who has caused the community unrest.

The Heartland Trilogy: Starts with Under the Empyrean Sky by Chuck Windings. Set in a wasteland of monster corn, the only crop that isn't outlawed, that isn’t safe for human consumption. Shadowed by floating cities above that treat the Heartlanders like slaves. The Empyrean government chooses each Heartlander's spouse and future. The only way out? Hope you win the lottery and get to join the Empyrean elite on the sky flotillas…but how likely is that? (The 2nd book is the best in my opinion but it's a unique story I wish more people noticed.)

and one because you're a gamer c:
The Unfortunate Decisions of Dahlia Moss by Max Wirestone: Dahlia Moss accepts money from a mysterious eccentric to solve a theft, granted she isn't a detective...and the theft took place in an MMORPG. A goofy who-dun-it? with a heroine as clueless as the average reader.

1) The Forever War
2) Only Human

Find 'Found'.

In case you've not read them, I recommend the Dresden Files- a series of books about a modern day wizard detective in Chicago.
Also, in case you haven't read it, I very highly recommend Jonathan Strange & Mr. Norrell, a hefty fantasy story about wizards in the Victorian era, that almost reads like a history book from the time (except actually fun to read), with footnotes and backgrounds and side-stories worked into the text.

One of the series I've enjoyed recently is the Mistborn series. I would recommend it to anyone who enjoys reading Fantasy.

As you may know, the Witcher games are based on a series of books. If you like fantasy, I recommend these books. There are:

-2 collections of short stories (The Last Wish, Sword of Destiny)

• 5 books which make up the main Witcher saga (Blood of Elves, Time of Contempt, Baptism of Fire, The Tower of the Swallow, The Lady of the Lake)
• and 1 standalone book which doesn't add much to the story in my opinion (Seasons of Storms)

I have actually read all of these, then immediately after that I started playing all three Witcher games and then I read the main saga again. In my humble opinion, it adds much more to the games if you read the books. But even without the games, they are very good fantasy books.

Regarding Sci-Fi, I quite enjoyed reading Daemon and Darknet written by Daniel Suarez. It's about a hyper intelligent computer virus gathering more and more power and about the people who try to stop it while trying to figure out what the ultimate goal of the virus is. It's a great story for anyone interested in modern technology although I think that it becomes a bit too over the top at some points.

Do you know Terry Pratchett?

His books are so well written, funny and absurd.

If you're a fan of middle-earth fantasy, i'd recommend to you

The Dwarves (by Markus Heitz)
Orcs: First Blood (by Stan Nicholls)
The Elven (by Bernhard Hennen)

I've read them (and all but one of their sequels, too) and really fell in love with them.

Isaac Asimovs foundation and robot books, best sci fi I’ve ever read

I mostly read fantasy, a big fan of R. A. Salvatore's Forgotten Realms as well as Margaret Weis and Tracy Hickman's Dragonlance novels, though I am sure you are aware of them. I did stumble upon two other great authors that I thoroughly enjoy:

• Jacqueline Carey's Kushiel's Legacy
• Sara Douglass's Wayfarer Redemption

My favourites for...
Science Fiction - The Lost Fleet by Jack Campbell (John G. Hemry)
Fantasy - The Magician Series by Raymond E Feist
Modern Fantasy (Action Thriller) - Anything by Matthew Reilly

The Lost Fleet is amazing for a more real version of futuristic space battles, where faster than light warships and fleets don't stop to duke it out like in Star Trek / Star Wars but instead clash at full speeds. It highlights points like the issues of how many hours ago a faster than light fleet you are seeing arrive in the system now (and where have they gone since then) as well as computer targeting systems struggling at near light speeds. Later books also bring Alien races into the series, all completely unique but logical in their design. Absolutely great series of very hard to put down books.

The Magician Series is a massive series by Raymond E Feist, over 30 decent sized books from memory with many persistent characters and a timeline that can span creation itself. Some of the books are a bit touch and go, I believe he gets rushed by his publisher on occasion and it sometimes shows but most of the books are amazing. Originally his group of friends designed their own Dungeons and Dragons world and created it with a major effort for realism. That world became the foundation for this series. He's also an author that actually pumps out high quality books consistently and often, not like George R.R. Martin who although does some unequaled amazing books is so slow we are probably going to all die of old age before one of his grand children finishes Game of Thrones...

Anything by Matthew Reilly is awesome, he has quite a few books out, several different persistent characters in different series with some crossovers. The books are all modern era but are like Indiana Jones meets Rambo, then added more steroids.

• Hitchhickers Guide to the Galaxy (all time classic)
• Metro 2033 (first book of the metro series if you like books that became video games)
• The Last Wish (first book of the witcher series again if you like books that became video games)
• The Stand (classic stephen king novel, about 1300 pages long)
• It (classic stephen king horror, i'm currently reading this, 1100 pages long)
• Dark Tower series (stephen king again)
• Do Androids Dream of Electric Sheep? (Bladerunner movie)
• American Gods (Neil Gaiman, became tv series)
• Good Omens (Neil Gaiman, upcoming tv series)
• Altered Carbon (first book of 3, became a tv series)
• Fahrenheit 451( a bad movie came this year)
• Hobbit and Lord of the Rings books (if you like tolkien)
• Hunger Games series (modern classic that became a movie, 3 books)
• The Maze Runner series (became a movie)
• A Song of Ice and Fire series (Game of Thrones books)
• Throne of Glass series
• Prince of Thorns series
• Demon Cycle series

I'm also into sci-fi, fantasy and horror so this is a nice opportunity to see what others recommend

I read and recommend:

1. "The Hobbit or There and Back Again"
2. Trilogy "Lord of the Ring"
   My sister recommend:
3. Trilogy "The Hunger Games"
4. All parts "Game of Thrones"

These recommendations were rather obvious and you probably have already read. I think you may like the books of Carlos Ruiz Zafón, eg "Marina". It mixes reality with a mystery and a hint of horror;) Also, his other books are worth the order, but I do not remember if there is an element of sci-fi / fantasy etc...

Here's my recommendations:

• The Cabin at the End of the World
• Only Human
• Side Life

You cant beat an Iain.M.Banks book or Alastair Reynolds both sci-fi, both brilliant

Arthur C. Clarke is as good as it gets in hard sci-fi. Aside from the obvious Space Odyssey tetralogy, there's The Fountains of Paradise which I highly recommend.

James S. A. Corey: The Expanse
Kind of like A Song of Ice and Fire meets Firefly. :-)

Also, Wolfgang Jeschke: The Last Day of Creation
A sci-fi that inspired the story of the Original War game.

Ive been lately reading more comics than books Ill leave a few that I liked the most.
1) Nameless.
2) Black Science.
3) Chilling Adventures of Sabrina.
4) Fall of CTHULHU.

My recommendation is not a certain book. I recommend reading books - winners (sometimes nominees) of famous awards: Hugo, Nebula, Locus, etc. Usually, this is the really good books.
List of Science fiction awards
List of joint winners of the Hugo and Nebula awards

Of the more popular things I'd recommend the Hyperion Cantos by Dan Simmons, a four novel epic about space exploration, FTL travel and galactic politics.
Between the Strokes of Night by Charles Sheffield is an interesting novel that takes place in 2010 and 29000AD and has the same cast of characters appear in both timelines even though it is not about time travel

My all time favourite books are Steven Erikson's Malazan Book of the Fallen series and George R R Martin's Song of Ice and Fire series (as seen on TV 😅)
