'mischievous' is the definition.
Both the definition and answer are adjectives.
Perhaps you can see a link between them that I can't see?

'book full of twists' is the wordplay.
'book' becomes 'tome' (a tome is a book).
'full of' is an insertion indicator.
'twists' becomes 'ricks' (I can't explain this - if you can you should give a lot more credence to this answer).
'tome' going around 'ricks' is 'TRICKSOME'.
