I’m currently reading:
The Wheel of Time
A Song of Ice and Fire
Dresden Files
The Way of Kings by Brandon Sanderson (well, that’s the name of the first book) (another huge epic fantasy, only one book out, looks very promising)
The Change by SM Stirling (all technology stops working in the modern world, what happens then, and now 25 years later)
Destroyermen by Taylor Anderson (WWII American destroyer transported to alternate version of the world where evolution went in a very different direction and the dominant species are velociraptors and super-lemurs)
Without Warning/After America by John Birmingham (a mysterious cloud kills nearly every living being in the USA in an instant, how the world changes/reacts)
Honor Harrington by David Weber (ongoing space opera about a scrappy star kingdom contending with its neighbors)
Off Armageddon Reef by David Weber (sci fi series about a planet settled in the far future by people who try to maintain their descendants at a low level of technology for complicated reasons, and a super-awesome-robot who wants to change things)
The Twelve Houses by Sharon Shinn (fantasy novels with a strong bit of romance) (not sure if more are being written)
1632/Grantville by Eric Flint and David Weber (American town is transported back in time to 17th century Germany, much intrigue and battle ensues) (there are many subseries in this series, I generally read the main ones, and I’ve enjoyed some of the side ones).
Until quite recently I devoured every one of the Bob the Nailer books by Stephen Hunter (sniper-oriented thrillers), but the most recent one was insultingly awful.
The Family Trade by Charles Stross (modern American woman learns she can transport herself to an alternate timestream Earth, a talent she apparently inherited from her estranged family, who she then comes back into contact with)
