Okay, I usually don't rec stuff to folks, but this one is pretty awesome. It's a Teen Wolf/Avengers crossover which shouldn't work as well as it does. So far there are two parts and both are done and both on the longer side. It's a non-linear story telling but it really works. It's about a Stiles owning his magic and becoming a Warden and the dynamics of family and friendship and duty and long-term plans and I think you should give it a read.
