frankenstein

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

'book' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I can't see?

'open fantastically intense' is the wordplay.
'open' becomes 'frank' (synonyms).
'fantastically' indicates an anagram (a fantastical ordering of the letters).
'intense' with letters rearranged gives 'enstein'.
'frank'+'enstein'='FRANKENSTEIN'

Can you help me to learn more?
