Im pretty new to Sci-fi, (Im more of a fantasy guy), but I have these two on my shelf and Im ready to go on to something new.
A Fire Upon the Deep by Vernor Vinge
Hyperion by Dan Simmions.
Ive only read The Terror by Dan Simmions, which I honestly didnt like, but otherwise Im brand new to these authors.
Im looking for something with more plot twists and adventure.
