According to The A to Z of Fantasy Literature, hard fantasy stories are “faithful to historical and anthropological data." Very little is left to chance, and every magical element has a story deeper than it seems on the surface. 

If you like your fantasy rational and complex, then these hard fantasy books are the adventures you're craving.

Waldo and Magic, Inc.

By Brandon Sanderson

The first book in Brandon Sanderson's epic fantasy trilogy of the same name, Mistborn takes place in the Final Empire. The world of Scadrial is oppressed by a dark ruler, and unlikely heroes are thrust into responsibilities they never could have imagined. 

Sanderson's series makes easy (and addictive) reading, but it's also a prime example of hard fantasy, in part because of the effort Sanderson put into making the magical system of allomancy so detailed and consistent.
