She quickclaimed my house to her.she tried before to have me sign papers hopping I wouldn't read them to sell my home to her for $1.00.What can I do??

A lot will depend on the wording of the power of attorney, but you sue her for fraud, and try to get a judgement for the value of the property, or hope she will sign house back over.

Time to get an attorney

First, you cancel the POA.

Then, you sue to set aside the quitclaim deed.
