During her short time as a ward in Queen Marguerite's Lancastrian court, fifteen-year-old Isobel has had many suitors ask for her hand, but the spirited beauty is blind to all but Yorkist Sir John Neville. It is nothing short of a miracle when the Queen allows Isobel's marriage to the enemy, albeit at a hefty price.

All around Isobel and John rages a lawless war. It is only their passion that can see them through the bloody siege of London by the Duke of York, the violent madness of Queen Marguerite, and the devolution of Isobel's meek uncle into the Butcher of England. For theirs is an everlasting love that fears not the scratch of thorns, from either the Red Rose or the White.
