The Red Queen (The Plantagenet and Tudor Novels #3) by Philippa Gregory

The second book in Philippa's stunning new trilogy, The Cousins' War, brings to life the story of Margaret Beaufort, a shadowy and mysterious character in the first book of the series - The White Queen - but who now takes centre stage in the bitter struggle of The War of the Roses.

The Red Queen tells the story of the child-bride of Edmund Tudor, who, although widowed in her early teens, uses her determination of character and wily plotting to infiltrate the house of York under the guise of loyal friend and servant, undermine the support for Richard III and ultimately ensure that her only son, Henry Tudor, triumphs as King of England.
