Spike gets bitten by a shark

Hi all,
I've been taunted trying to remember the fiction with the following scene. It takes place between seasons 3-4 of Angel / season 6-7 of BTVS. Buffy & Spike go to LA to help out AI search for Angel, after Connor dumps him in the ocean. The boat they use to search the ocean is owned by a part demon. Spike dives into the water to release Angel and while down there a shark attacks him and bites him on the side. Does anyone remember the fiction & author with this sequence?

Tempus de Muto by Schehrezade

Oh yes. That's it. I have to reread this again even though it's WIP. There's so many scenes that keep on coming to my mind. The story is so well written and many scenes are memorable. It's a shame it looks to never be finished.
