Book excerpt: International bestselling author Guy Gavriel Kay's latest work is set in a world evoking early Renaissance Italy and offers an extraordinary cast of characters whose lives come together through destiny, love, and ambition. In a chamber overlooking the nighttime waterways of a maritime city, a man looks back on his youth and the people who shaped his life. Danio Cerra's intelligence won him entry to a renowned school even though he was only the son of a tailor. He took service at the court of a ruling count—and soon learned why that man was known as the Beast. Danio's fate changed the moment he saw and recognized Adria Ripoli as she entered the count's chambers one autumn night—intending to kill. Born to power, Adria had chosen, instead of a life of comfort, one of danger—and freedom. Which is how she encounters Danio in a perilous time and place. Vivid figures share the unfolding story. Among them: a healer determined to defy her expected lot; a charming, frivolous son of immense wealth; a powerful religious leader more decadent than devout; and, affecting all these lives and many more, two larger-than-life mercenary commanders, lifelong adversaries, whose rivalry puts a world in the balance. A Brightness Long Ago offers both compelling drama and deeply moving reflections on the nature of memory, the choices we make in life, and the role played by the turning of Fortune's wheel.
