Dim element deprived of love the second time in a fantasy trilogy (8)

'a fantasy trilogy' is the definition.
(book trilogy by Alison Sinclair)

'dim element deprived of love the second time' is the wordplay.
I cannot really understand how this works, but
'dim' could be 'dark' (similar in meaning) and 'dark' is found in the answer.
'element' could be 'rn' (Rn is an example) and 'rn' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
'second' could be 'b' (B can mean second eg B-side) and 'b' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...

'in' acts as a link.
