Lots of details need to be added. Like, you can't just have the woods by moonlight, but these trees and roads and where the moonlight actually reaches. And the house they go to has to be described, and it's got to be eccentric. (Possibly more as advertisement than out of pure eccentricity.)
And then I come to the attack and realize that if the heroine is, at this stage, to have a decisive effect, there will have to be only one attacker. And though it's a part that's one and done and the character will never be seen again, the superpowers will need to be more clarified. Ah, development.
