I can recommend Sanity. One of my favorite Heinlein stories, Gulf, featured a secret society of superachievers who banded together to save humanity from itself. Heinlein’s story didn’t quite live up to the promise of its premise, but Neovictorian’s Sanity, does. Recruited since high school by a similar secret society, Cal Adler has to figure out their motives and decide whether to enlist their aid to avenge his friend’s death. Written in an interesting non-linear style, Sanity is part mystery, part thriller, and part anti-modernist critique. Neovictorian constructs a well-grounded and plausible secret history of the Cold War and the behind-the-scenes struggle to control the destiny of our society. If you like my books, you’ll probably like Sanity.
