Way to make love by the book (5)
I believe the answer is:
novel
'the book' is the definition.
(novel is a kind of book)
'way to make love by' is the wordplay.
'way' becomes 'n' (Compass direction - North**).
'to make' is an anagram indicator.
'by' says to put letters next to each other.
'love' with letters rearranged gives 'ovel'.
'n'+'ovel'='NOVEL'
(Other definitions for novel that I've seen before include "Rebecca?" , "Hitherto unknown" , "work of Dickens?" , "Of a kind not seen before" , "Fresh" .)
