Queen of Shadows — Edith Felber

It is fourteenth-century England. Wales has been brutally crushed, while Scotland's brave hearts remain rebellious. With treason everywhere, England's beautiful Queen Isabella -- humiliated for years by her weak, unfaithful husband -- is emerging from the shadows to take her revenge. But there is another -- equally forceful and cunning -- who pretends to be what she is not so that she may avenge the blood of Wales…

At twenty-one, Welsh native Gwenith de Percy is newly sent to be handmaiden to Queen Isabella. Sworn to a secret mission, Gwenith is astonished by the court's power and devastated that her vow to avenge Wales seems hopeless. Although Isabella is wife to her mortal enemy, Gwenith cannot hate the queen, who is herself a victim of Edward's unfitness to rule.

For Isabella, her once-golden marriage is now her penance. Because of Edward's rumored relations with men, Parliament has forced him to share his throne -- a demeaning arrangement that torments Isabella. With the help of her secret noble lover, Roger Mortimer -- an enemy of her husband, imprisoned in the Tower of London -- the queen plots to take control. And so two women who are the unlikeliest of allies set out to change the course of history....
