The Hundred Thousand Kingdoms by N.K. Jemisin
An incredible secondary-world fantasy that combines living mythology with practical magic in completely unexpected ways. Yeine Darr has been chosen as one of the heirs of the Arameri empire, and must navigate the perils of court intrigue and the machinations of enslaved gods. Wildly original and gorgeously written, full of danger, sensuality, and wonder. An unbelievable debut by a truly talented author. Highly recommended.
