One,

How old is your dd? The Lemony Snicket: A Series of Unfortunate Events is a FABULOUS series for vocabulary. My dh read all 13 to my girls starting when my youngest was just five. She loved them but they are bit on the dark side. If you want something a little friendlier the Beatrix Potter books have wonderful words but unlike Snicket they don't build in the definitions.

Enjoy
