"Relics of a mysterious god, the Spice Gates connect the eight far-flung kingdoms, each separated by a distinct spice and only accessible by those born with a special mark. This is not a caste of distinction, though, but one of subjugation: Spice Carriers suffer the lashes of their masters, the weight of the spices they bear on their backs, and the jolting pain of the Gates themselves. Amir is one such Spice Carrier, and he dreams of escaping his fate of being a mule for the rich who gorge themselves on spices like the addicted gluttons they are. More important than relieving his own pain, though, is saving his family, especially his brother, born like him with the unfortunate spice mark that designates him for a life of servitude. But while Amir makes his plans for freedom, something stirs in the inhospitable spaces between the kingdoms. Fate has designs of its own for Amir, and he soon finds himself drawn into a conspiracy that could disrupt the delicate dynamics of the kingdoms forever."--Dust jacket.
