Booktrack Edition: The Tower of Babel is the greatest marvel in the world. Immense as a mountain, the ancient Tower holds unnumbered ringdoms, warring and peaceful, stacked one on the other like the layers of a cake. Soon after arriving for his honeymoon at the Tower, the mild-mannered headmaster of a small village school, Thomas Senlin, gets separated from his wife, Marya. Senlin is determined to find Marya, but to do so he'll have to navigate madhouses, ballrooms, and burlesque theaters. He must survive betrayal, assassins, and the illusions of the Tower.

Marcus' hero days are behind him. He knows too well that even the smallest war still means somebody's death. When his men are impressed into a doomed army, staying out of a battle he wants no part of requires some unorthodox steps. Cithrin is an orphan, ward of a banking house. Her job is to smuggle a nation's wealth across a war zone, hiding the gold from both sides. She knows the secret life of commerce like a second language, but the strategies of trade will not defend her from swords. Geder, sole scion of a noble house, has more interest in philosophy than in swordplay.

Twenty-seven years ago, a Duke with a grudge led a ruthless coup against the empire of Semilla, killing thousands. He failed. The Duke was executed, a terrifyingly powerful sorcerer was imprisoned, and an unwilling princess disappeared. The empire moved on. Now, when Quill, an apprentice scribe, arrives in the capital city, he believes he's on a simple errand for another pompous noble: fetch ancient artifacts from the magical Imperial Archives.

Erika ja Leora is a powder mage in northern Kez, a place where that particular sorcery is punishable by death. She is only protected by her family name and her position as heir to a duchy. When she decides to help a young commoner-a powder mage marked for death, fugitive from the law-she puts her life and family reputation at risk and sets off to deliver her new ward to the safety of Adro while playing cat and mouse with the king's own mage hunters and their captain, Duke Nikslaus.

Zilan dreams of becoming a royal alchemist, of providing for her family by making alchemical gold and gems for the wealthy to eat in order to stay young forever.

When Zilan finally has the chance to complete her imperial exams, she ventures to the capital to compete against the best alchemists in the country in tasks she’ll be lucky to survive, let alone pass.
