Holiday House Daughter of the white rose, hardcover/diane zahler

Can a common girl save a prince trapped in the Tower of London? April.

England.

The king is dead.

Long live the king.

Nell Gould is the daughter of the royal butcher, a commoner, but she has been raised as the playmate of King Edward and Queen Elizabeth's royal children: Princess Cecily, Princess Bess, Prince Dickon, and Prince Ned, heir apparent and Nell's best and closest friend.

They think alike, her and Ned, preferring books and jousts to finery and gossip.
