Stiles and his father have been the only two werewolves in Beacon Hills since they moved there seven years ago. In fact, Stiles had never even met another wolf that wasn't related to him. Which would be fine except that he was a Delta - a Third, a Breeder, whose only purpose in life was to find a nice big, strong Alpha or Beta to breed them like the bitch he apparently was. But, again, given the lack of werewolves, Stiles pretty much thought he'd never have to deal with any of that.
Then one night his father gets called out to a murder scene in the Preserve and Stiles can't help but go check it out.
Stiles thought college would be different, but no, here he is, being chased by a slobbering beast that wants to crunch his bones. And along comes Derek Hale (still as hot as ever) to help Stiles escape... and along the way, change his life forever.
It’s a popular joke among Alphas: fuck an Omega, get heartbreak on your hands. Omegas are fragile little emotional things, needy and whiny. Stiles refuses to become that, or to believe that he’s anything like that.
Stiles and Derek have been fuckbuddies for a while when Derek loses his memories of the past three years - and them - in an accident. (Also - everyone's a werewolf, and everyone's alive.)
