HYDRA's Tesseract (Title in progress)

Y/N is the so-called “sister” of Wanda Maximoff, but they aren’t related by blood. Sisters by choice. Wanda has always been a role model for Y/N because she taught her how to control her powers, which were very similar to Wanda’s. Life had been normal, except for the occasional “someone stole the Tesseract and opened a portal!” But Y/N’s world crashes as HYDRA begins to invade Stark Tower, taking some of the team members. As S.H.I.E.L.D. fights against one of the biggest threats they’ve ever faced, Y/N finds herself falling for someone in the mess of it all. And when they’re taken by HYDRA, will she be able to save them, and everyone else?
