Since I first read Sanderson's Mistborn series, I've been a fan. Mistborn took a common fantasy trope, that of the Chosen Hero of the Ages, and inverted it, which made for a pretty fun and interesting read. 

In Sanderson's latest novel, Steelheart, Sanderson once again finds a common trope and inverts it, this time that of the advent of superpowered humans who, in Sanderson's version, are corrupted by their superpowers and become tyrants that rule over humanity. Called "Epics," these beings are sociopaths of the highest order, considering unpowered humans to be insects that they were born to rule.
