I have ringworld in one of my many books piles somwhere....
Right now I'm reading the first book in the Mist Born series by Brandon Sanderson.
I enjoy his works for their vast world building, their character progression and the unique systems of "magic" that he employs in his worlds.
I mostly read fantasy series or sci-fi but I have the awful habit of buying whole series if they look neat and not actually reading them so I have stacks and stacks of books that I haven't read yet, its actually starting to look like my steam library now lol
