A new can inside unconventional book (9)

Ross

I believe the answer is:

antinovel

I'm a little stuck... Click here to teach me more about this clue!

'book' is the definition.
(I have seen 'experimental book' mean 'antinovel' so perhaps 'book' could also mean 'antinovel')

'a new can inside unconventional' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is found in the answer.
'new' could be 'novel' (similar in meaning) and 'novel' is found in the answer.
The remaining letters 'ti' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for antinovel that I've seen before include "work of fiction" , "Unconventional story" , "experimental book" .)

I've seen this clue in The Daily Express.
