where is 'Seize the Night'?

[ladyhatshepsut.livejournal.com]

 In clearing out duplicate files to make room for new fanfic I came across the remnants of a file entitled 'Seize the Night' with the notation "Darla mothers Willow."  Since there's no file to open I have no author or website to lead me to finding it again.  Can anyone help me?
