Books involved in storm and chatter (6)
I believe the answer is:
gabble
'chatter' is the definition.
('gabble' can be a synonym of 'chatter')
'books involved in storm' is the wordplay.
'books' becomes 'bb'.
'involved in' indicates putting letters inside.
'storm' becomes 'gale' (I've seen this before**).
'bb' put within 'gale' is 'GABBLE'.
'and' acts as a link.
(Other definitions for gabble that I've seen before include "Speak quickly and unclearly" , "Chatter inarticulately" , "Talk quickly and indistinctly" , "Fast unintelligible talk" , "Speak quickly and incessantly" .)
