Book excerpt: Welcome to Tremontaine, where ambition, love affairs, and rivalries dance with deadly results. In this serial, Ellen Kushner and a team of writers return readers to the world of scandal and swordplay introduced in her cult-classic novel Swordspoint. Readers familiar with the series will find a welcome homecoming while new fans will learn what makes Riverside a place they will want to visit again and again. Tremontaine follows Diane, Duchess Tremontaine, whose beauty is matched only by her cunning; Rafe Fenton, a handsome young scholar with more passion than sense; Ixkaab Balam, a tradeswoman from afar with skill for swords and secrets; and Micah, a gentle genius whose discoveries herald revolution. Sparks fly as these four lives intersect in a world where politics is everything, and outcasts are the tastemakers. Tread carefully, dear reader, and keep your wit as sharp as your steel.
