Okay so I have a fic that I've been looking for for sooo long! I'm pretty sure it was on AO3 as that's generally the only place I read fics, and I'm pretty sure it was Sterek (usually what I read) but it might not be. I don't remember what other characters are in it so I haven't tagged them, but I'm pretty sure they're mostly all in it. It's probably a longer fic, but I really don't have a lot of information to go off!
The only thing I can definitely remember from this fic is that Stiles leaves Beacons Hills and makes it look as though he's driven his jeep off a cliff so the pack and his dad think he's dead, but he wasn't actually in it. I think I remember other stuff but I'm not sure about it- I feel as though it was because he was being neglected in the pack? But this might not be the reason. Also I'm pretty sure Derek never gives up looking for him, even when the rest of the pack eventually do? But like I said, I'm not sure, and they could be from completely different fics. He comes back to Beacon Hills in the end.
I've looked for this everywhere and asked in all sorts of places and can't find it, I have a feeling it might have been deleted but I'm really hoping it hasn't!
