Raisa of Upper Earth has only lived a life of privilege and acquiescence. Ever dutiful, she accepts her father's arrangement of her marriage to Lein, Crown Prince of the corrupt, volatile lands of Lower Earth. Though Lein is a stranger, Raisa knows the wedding will unite their vastly different worlds in a pact of peace: an infusion of Upper Earth technology will usher in the final age of enlightenment, ending war between humans forever. Or is justice more urgent?
