The honest answer is that it depends almost entirely on what she did with those two years inside, and you probably already know the answer better than you think.
Parole boards are not complicated in what they look for. They want to see that an inmate followed the rules, stayed out of disciplinary trouble, and engaged with whatever programming her counselor recommended. Substance abuse treatment, educational courses, vocational training, anger management, whatever was on her program plan, completion of those things signals to the board that she took her time seriously and is not walking out the same person who walked in.
A non-aggravated 8-year sentence with a parole hearing at two years is a setup that gives her a real shot. The system is not designed to keep people like her indefinitely. It is designed to release people who demonstrate they are ready, and two years is enough time to build a solid record if she used it well.
If she was a model inmate, stayed clean of write-ups, completed her programming, and her counselor is prepared to speak positively on her behalf, the odds are in her favor. Counselor support matters more than most people realize going into that room.
If there were incidents, disciplinary infractions, or incomplete programming, the board will weigh those against her. It does not automatically disqualify her, but it gives them reason to hesitate.
The best thing you can do before August 27th is make sure she has a solid release plan documented, a stable address, confirmed support, and ideally employment prospects. Boards want to see that someone has somewhere real to land.
