Pop padding novel summary with many, many pages (5,4)
I believe the answer is:
cream soda
'pop' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cream soda that I've seen before include "Vanilla-flavoured fizzy drink" , "Carbonated soft drink" , "Vanilla-flavoured pop" , "Sparkling stuff" .)
