Child Abuse?

Question

Child Abuse?
My niece and nephew say their mother emotionally abuses them. She also keeps them in their house and has them do chores from a.m till bed which is priority over school work during school. She moves them and hides them from us Dads amily. Their Dad is no longer a part of their lives so I am lost on what I can do to help them. Next school year they begin homeschooling my niece starts high school next year. They are both against it but fear saying that to their Mom in fear of punishment. They both want to live with me or their grandmother but we are at loss of what we can do according to California law. They also say their Mother does drugs but I have no physical proof of anything. Help please
