I recommend the following biographies.
 

David Starkey, Elizabeth

Alison Weir, Elizabeth the Queen

Anne Somerset, Elizabeth I

Wallace MacCaffrey, Elizabeth I

Jasper Ridley, Elizabeth I

Elizabeth Jenkins, Elizabeth the Great
 

I also recommend the series of books written on Elizabeth by Alison Plowden. These have recently been republished.
 

Novels are also a great way of bringing history alive, especially if they are well researched and written. I would recommend the following novels on the life of Elizabeth I:

Rosalind Miles, I, Elizabeth

Susan Kay, Legacy

Jean Plaidy, Queen of this Realm
