Wrapping of pet novel unexpectedly inspiring soldiers (11)
I believe the answer is:
envelopment
'wrapping' is the definition.
(thesaurus)
'pet novel unexpectedly inspiring soldiers' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'novel' is 'nvelo' which is within the answer.
'soldiers' could be 'men' (men can mean a group of soldiers) and 'men' is present in the answer.
an anagram of 'pet' is 'ept' which is within the left over letters.
No letters remain.
This explanation may well be incorrect...
'of' is the link.
(Another definition for envelopment that I've seen is " investment".)
