Mine would be Alex Scarrow with the Timeriders series he's done,
Max Brooks for WWZ and Zombie Survival Guide,
Karen Traviss for her books in the halo series(Kilo-5 trilogy) and Star Wars: Republic Commando series.

Any others?

Tolkien.... because... well... Tolkien.

Next would be R. A. Salvatore.

Angela Carter for all her fantastic books and short stories.
Robert Holdstock for the weird and wonderful Mythago Wood series and the very creepy Night Hunter series (writing as his alter ego Robert Faulcon)
Sheri S. Tepper for the Grass trilogy.
Mervyn Peake for the superbly grotesque Gormenghast.
Emily Bronte for Wuthering Heights.

LOTR is the only book I've ever read 17(soon to be 18) times.

Neil Gaiman, american gods is one of my favorite books

And an honorable mention to steven king, His door stopper books really helped the bus ride to my house during high school

It's hard to pick just one author that I like. I guess I'll go with Dan Brown. I enjoy his falsified history. I feel like he went too mainstream. I didn't like his last book, Lost Symbol too much though.

I'm starting to like Stephen King a bit more, but I'm struggling finding the time to finish a book I started of his almost a year ago.

J. K. Rowling is also a childhood favorite of mine, and always will have a special place in my magical imagination.

I also think Michael Crichton was wonderful.

Tolkien
Rowling
Gregory Keyes
Drew Karpyshn

They are my 4 favorite authors, I love their books.

While I have many favorites I adore reading Tom Robbins books. Just so out of the ordinary. Kurt Vonnegut, O. Henry, William Faulkner, Mark Twain, Steinbeck...I've a long, long...very long list of favorites. Still Tom Robbins comes to mind first whenever I am asked.

Margaret Atwood. She's my all time fave. Her most notable novels for me would The Handmaid's Tale and Oryx and Crake. I've always liked authors who wrote very descriptively and with a lot of internal dialogue by the main characters. She writes exactly like that.

Marion Zimmer Bradley would probably run a close second.

Adrian Goldsworthy for his fun-to-read contributions to to my pauper's library on ancient Roman history.
Christopher Hitchens for his wisdom, invaluable prose and immaculately barbed writing voice.
Clive Barker for my favorite childhood novel The Thief of Always.
David Irving for his staunch and noble stand in the face of persecution and ignorance on a global scale.
Saint John for having [censored] up dreams and ruining my life.
C.S. Lewis for positing in his The Screwtape Letters the idea that demons might actually be trying to keep us alive.
Robert A. Heinlein for knowing what it means to be a citizen.
Saint Augustine for teaching me how to defend any argument, no matter how preposterous.
Robert Frost and Edgar Allen Poe for being the only American authors worth their salt.
Maya Banks for proving that complete asstastic garbage can be a best-seller.

Tolkien - Because it's god damned Tolkien.

Orwell - Main reason why I'm the cold-hearted cynical pessimistic bastard I am.

Crichton - I think his stories are an absolute joy, and rather weighty in the cautionary department.

R. R. Martin - Author of my favorite on going series today.

Dan Brown - Overrated? Yes. Not exactly historically accurate? Yes. Say what you will, Angels & Demons remains among my very favorite books.

I haven't read any of Dan Brown's works, but I did see the films DaVinci Code and Angels & Demons... I thought I hated the DaVinci Code because it was all "Dun-dundun dun-dundun Tom-Tom Hanks-Hanks! Dun-dundun dun-dundun Mag-Ne-To."until I saw Angels & Demons and it was just straight garbage on a whole new scale to the point where it wasn't even amusing.

Books were way better. He is extremely overrated, but I liked him before he was mainstream. Digital Fortress and Deception Point were great. I hope he writes again, but ends his Robert Langdon character.

Movie is [censored] compared to the book.

The essence of hipster.

Yeah, it's probably the Robert Langdon character that keeps me from reading the books... one crazy ass conspiracy per person, please.

Neil Gaiman, Chuck Palahniukiukjdiofahdfj, Orson Scott Card, and Terry Pratchett.

Neil for his modern mythology and all in all excellent writing skills.

Chuck for his writing style, which seems very particular to him. His recent stories have been a bit lackluster, but Survivor, Rant, Choke, and Fight Club are some of the best psychological thrillers I've ever read.

Orson because I grew up reading the Ender's Game novels.

Terry for his wit.
