If you're a big fan of Phillipa Gregroy's writing then you'll be delighted to hear that her novel, The Cousins' War, had been adapted for the small screen. We're sure this epic historical drama will be easily watched without prior knowledge of the book though. England has been at war for 9 years (The War of The Roses to be precise) and nobody can decide who should be king. Edward IV is crowned with the help of the Earl of Warwick - but when the monarch falls in love with beautiful widowed commoner Elizabeth Woodville, things get complicated.
