Here's some information about Karen Azinger:
Karen L. Azinger has always loved fantasy fiction, and always hoped that someday she could give back to the genre a little of the joy that reading has always given her. Eight years ago on a hike in the Columbia River Gorge she realized she had enough original ideas to finally write an epic fantasy. She started writing and never stopped. The Steel Queenis her first book, born from that hike in the gorge. Before writing, Karen spent over twenty years as an international business strategist, eventually becoming a vice-president for one of the world's largest natural resource companies. She's worked on developing the first gem-quality diamond mine in Canada's arctic, on coal seam gas power projects in Australia, and on petroleum projects around the world. Having lived in Australia for eight years she considers it to be her second home. She's also lived in Canada and spent a lot of time in the Canadian arctic. She lives with her husband in Portland Oregon, in a house perched on the edge of the forest. The first four books of The Silk & Steel Sagahave already been written and she is hard at work on the fifth and final book.
And here's a decription of The Steel Queen:
Azinger's series is fast-paced action-packed fantasy. In a medieval world of forgotten magic, mortals are lured to the chessboard of the gods where an epic struggle of lives, loves and crowns hang in the balance, yet few understand the rules. In this game of power, the pawns of light and darkness will make the difference in the battle for the kingdoms of Erdhe: Katherine, "The Imp": a young princess with the stout heart of a warrior will challenge the minions of a thousand-year-old evil. Liandra: The Spider Queen; who uses her beauty to beguile, her spies to foresee, and her gold to control, will need all of her skill and strength to fight a rebellion with her own blood at it's heart. Steffan, the puppeteer, will corrupt the innocent and unwary with greed and desire, as he sets an entire kingdom ablaze.
