Just in case you're oblivious to
cj2017's new fic,
Breaking Point (part 1), I highly recommend it. As she describes it, the story involves the whole team with a definite Sarah/Derek bias. It follows from her previous fic (she's got a link to it), but stands on its own just fine if you're coming in fresh. Go and enjoy.
ETA: Why read just one fic when you can read two?
Sabaceanbabe has a group of five awesome mini-fics (
Scars You See, Scars You Don’t) about the physical and emotional scars that mark the characters of TSCC.
