Mr. Gray sets an impossible condition for their marriage—Zadock must deliver a sealed and highly secretive letter to General Irion, fighting one thousand miles southwest, deep within the embattled and newly independent Republic of Texas. The fate of the Union lies within the mysterious contents of that sealed letter, but that is only the beginning . . .     Three hundred years later, in the dystopian city-state of the Texas Republic, Zeke Thomas has just received news of the death of his grandfather, an esteemed Chicago senator. The world has crumbled. Paper documents are banned, citizens are watched, and dissenters are thrown over the walls into "the rot." When Zeke inherits—and then loses—a very old, sealed letter from his grandfather, Zeke finds himself and the women he loves at the heart of a conspiracy whose secrets he must unravel, if it doesn't destroy his relationship, his family legacy, and the entire republic first.     The two propulsive narratives converge through a wildly creative assortment of documents, books within books, maps, notes, illustrations, and more. Zach Dodson has created a gorgeous work of art and an eye-popping commercial adventure for the 21st century.From the Hardcover edition.
