Maybe new book with nothing in it (5)
I believe the answer is:
album
'maybe new book' is the definition.
'album' can be an answer for 'book' (I've seen this before). I'm not certain of the 'maybe new' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for album that I've seen before include "Book for keeping photos, stamps, etc" , "Book for organising photographs" , "Book for stamps/photos" , "place for photos" , "Book for displaying a collection" .)
