Kushiel's Dart by Jacqueline Carey
"A nation born of angels, vast and intricate and surrounded by danger... a woman born to servitude, unknowingly given access to the secrets of the realm...
Born with a scarlet mote in her left eye, Phédre nó Delaunay is sold into indentured servitude as a child. When her bond is purchased by an enigmatic nobleman, she is trained in history, theology, politics, foreign languages, the arts of pleasure. And above all, the ability to observe, remember, and analyze. Exquisite courtesan, talented spy... and unlikely heroine. But when Phédre stumbles upon a plot that threatens her homeland, Terre d'Ange, she has no choice.
Betrayed into captivity in the barbarous northland of Skaldia and accompanied only by a disdainful young warrior-priest, Phédre makes a harrowing escape and an even more harrowing journey to return to her people and deliver a warning of the impending invasion. And that proves only the first step in a quest that will take her to the edge of despair and beyond.
Phédre nó Delaunay is the woman who holds the keys to her realm's deadly secrets, and whose courage will decide the very future of her world.
Not since Dune has there been an epic on the scale of Kushiel's Dart-a massive tale about the violent death of an old age and the birth of a new. It is a novel of grandeur, luxuriance, sacrifice, betrayal, and deeply laid conspiracies. A world of cunning poets, deadly courtiers, deposed rulers and a besieged Queen, a warrior-priest, the Prince of Travelers, barbarian warlords, heroic traitors, and a truly Machiavellian villainess... all seen through the unflinching eyes of an unforgettable heroine."
Mass market, a nice copy!
