Books about love seized by Poles (6)
I believe the answer is:
novels
'books' is the definition.
(novel is a kind of book)
'about love seized by poles' is the wordplay.
'about' is an anagram indicator.
'seized by' means one lot of letters goes inside another.
'poles' becomes 'ns' (north and south poles).
'love' is an anagram of 'ovel'.
'ovel' inserted within 'ns' is 'NOVELS'.
(Other definitions for novels that I've seen before include "Books for sloven" , "Books of fiction" , "Works of fiction" , "Long fictional tales" .)
