This is called "theft." You can take her to court in an effort to have the money returned. Rather then spending money you probably don't have to hire a lawyer for this, Small Claims Court may be your best approach. Small Claims Courts let you represent yourself and the rules are relaxed to make it easy for non-lawyers. Check the limits in your state -- it could be $5,000, $7,500 or a bit higher.
If your sister is insolvent, this may do you no good, as "you can't get water out of a stone."
You could also file a criminal complaint since she stole your money. She is your sister, so carefully think this through before you do it. Be sure you revoke the power of attorney. Do this in a simple writing and deliver it to any bank where you have an account. They must know that you and only you can access your money.
