My fave is fantasy, but for movies it is sci-fi. In both cases I like the escapism, love the imagination in creating alternate worlds, but any rules they create for physics or magic in their world must hold true in the story or I lose it.

I'm big into sci fi and fantasy. Yes I know the difference. No I'm not going to argue about the difference. I like both! Deal with it.

Biography
Horror

Nuts and bolts scifi. If astrogation and ships engineering is a big part of the story I'm all about it.

Well, as an author of SciFi/Fantasy/Romance I think that is where my favorite stories have come from and why I became an author myself. Of course I’ve only published two books so far. Working on the third now.

Sci-fi / fantasy horror.
Best example, The great and secret magic show, By Clive Barker

oddly enough, anything SF-ish with a religious angle. Book of New Good Things is an example.

Non fiction. I like reading about actual events

Easier to list the genres I don't like. Self help/ motivational, 19th century soap opera (Flaubert, Dickens et.al.), and technical manuals.

Nonfiction then Sci-Fi.

Historical fiction. Thinking back, I thought I would have been a sci-fi and fantasy "nerd". But apart from JRR Tolkien's work (TLOTR and Silmarillion) and Stephen Lawhead's Arthurian books (which he tied to the Roman Empire and the paganism of the British Isles - which is at the far edge of historical fiction) for fantasy and some Arthur C Clarke's works (Rama, 2001), I didn't pick up any other fantasy (e.g. Narnia) and sci-fi books (e.g. Ringworld - is that even sci fi? I don't know). I did read an Elric of Melnibone book which I found very interesting but it didn't "grab" me to continue reading the series.

In my mid twenties, I picked up, by random, Wilbur Smith's When The Lion Feeds. I got hooked on historical fiction since then. In the last few years, my chosen favourite is Patrick O'Brian's Master and Commander series. My books from these two authors outnumber any other genre in my collection.

Definitely Sci-Fi, but I also like many classics.

Scandinavian mystery stories. Icelandic, Norwegian, Swedish, Danish. Plus English mysteries.

Fiction. Most fiction? Sci-Fi, Horror, Fantasy, Suspense, Romance, Mystery and Crime Solving.

Not sure what the Pendergast series is categorized under? [en.wikipedia.org] Best if read in order,

Loads more just having a foggy brain day! J.R. Ward is a favorite. L.K. Hamilton.

I've laid off "the end of the world as we know it" books. Too real right now?

1. Spy novels. 2) Good courtroom drama.

I like almost all genres. I tend to read a lot of MM romances for a kind of odd reason - I got so frustrated with how authors were writing "strong" women. I found these women to be extremely selfish and cruel. I like smut because I can read it quickly over my lunch at work to decompress before heading back.

crime fiction but every so often go back to the old favourites teh classics

Non-Fiction, but I don't really read much anymore.

Horror, Mystery, Thriller, Suspense.

100 year old contemporary books. I enjoy the things that are "as out of fashion as a 15 stone chorus girl" to use a 1915 colloquialism. I enjoy reading how crowded and sweaty the NY electric train was at the turn of the century, OK one more century back.

Sci-fi, of the John Scalzi, Robert A. Heinlein kind, where there is a fun plot and plenty of character in the characters.

Next favorites, autobiographies/biographies of interesting people, including slave narratives, American Indian captive stories, LGBTQ people, famous people, fictional historical autobiographies, etc.

There are so many books to read in a variety of genres.
I like reading fantasy, history, historical fiction, political thrillers, to name a few.

Here recently I've been digging some Warhammer 40k sci-fi. I'm reading four different ones from that line of work.

Been trying to read bios on the Presidents of the U.S.

Been doing a little bit of reading in philosophy also. Reading a book based on the Meditations by Marcus Aurelius.

It's typical for me to be reading between 10 and 15 books at a time. I've tried to cut that down to under ten at time.

As to why do I like that genre? Well I don't think I truly answered your question. I cannot pick one genre as a favorite. Depends on what time in life the question is asked. But in all honesty, I have not cornered myself into favoring just one. Going to a bookstore or library or even my own bookshelves is like going to a buffet. I'm gonna try a little bit of everything! I like 'em all!

I like westerns. It is a genre that often doesn't get much respect, but it is a truly American genre and a wonderful vehicle for exploring the American Experience. Four books that won Pulitizer Prizes were books about Western themes - The Way West, The Travels of Jamie McPheeters, Angle of Repose, and Lonesome Dove. A.B. Guthrie and Larry McMurtry raised the Western novel to high literature. Wallace Stegner explored the Western perspective in his fiction and non-fiction. While I am not a fan of Louis L'Amour, I do enjoy Max Brand, Frank Gruber, and Cliff Farrell, among others. Recently, The Son, by Philipp Meyer, now developed into a miniseries, is another example of the rich storylines and characters that can be developed in Western-themed literature.

Police proceddure/detective mystery - Michael Connelly or law/lawyer procedural mystery - Grisham.
