Cracked Control by Viola Grace

Abduction, genetic modification, and a nap that crossed decades is just the start for one of the first Volunteers to enter the Citadel, thirty years late.

Addy was a lost Terran. Her ship was captured on the way to the Alliance training center, and she and the other occupants were held for experimentation.

Months of agony with her fellow humans dying under the test-to-destruction methods of the researchers ended the day that Addy was taken to the edge of her limits. A rescue operation came to save her and the other survivors, and she was sedated for the trip back to the Alliance.

Addy lay in stasis while the world she had set on its path to destruction shattered and the rescue shuttle fought for its own survival.

Thirty years later, Addy is woken to find that the world has changed, she is alone at a base, and she has the power in her cells to break the world under her feet. No pressure. Ha.
