Unfortunately, there is no recently published book that looks exclusively at the Queen's maids of honor. However, there is:

Violet Wilson's Queen Elizabeth's Maids of Honor and Ladies of the Privy Chamber (now out of print but perhaps obtainable via www.bibliofind.com)

Anne Somerset's book LADIES-IN-WAITING: From the Tudors to the Present Day ;

There is also an excellent unpublished Ph.D thesis by  Charlotte Merton, The Women that served  Queen Mary and Queen Elizabeth (Cambridge University)
