In this post I've added links to the homepages of three of my favorite authors: Stephen King, Jeffery Deaver, and Christopher L. Bennett
Stephen King needs no introduction. He's the writer I admire most and the one I most closely try to emulate. I've never read a King story that I've disliked, although there are some I like more than others. I haven't read all his books but I'm trying.
Jeffery Deaver is a thriller/mystery writer most well-known for his Lincoln Rhyme series. My favorite book by him is The Cold Moon. Deaver is known for his plot twists and reversals. While I think he occasionally stretches them, his books are fast-paced and difficult to put down. His prose and style are very different from King but I highly recommend him.
Christopher L. Bennett is a sci-fi writer that has written mostly tie-in novels, the most being for Star Trek. He brings hard science to his stories, with lots of technical details but his books are epic in scope and his world-building skills are admirable. His first original novel, Only Superhuman, is coming out this year and I'm looking forward to it. I'd recommend Star Trek: Titan - Orion's Hounds and Star Trek: Department of Temporal Investigations - Watching the Clock.
I hope you'll check out these authors. Are there any you would recommend? If so, say it in the comments box.
