Balloon Animals Are Awesome - DiscontentedWinter

An excellent first fanfic from DiscontentedWinter aka Lisa Henry. Author gets Stiles internal (and external) monologue to perfection, Derek's lack of communication is classic.

'So Stiles is not dancing to Ugly Heart, and he’s not belting the lyrics out at the top of his lungs, and he’s not totally absolutely fucking mortified when he spins around to find Derek Hale climbing in his window.'
