Echo was talking to the children telling stories like she always does. She never stops talking no matter what. Whenever someone asks her a question she talks about something else.
The Queen came along asking were Zues was. Instead of Echo answering the question she just carried on with something else. The Queen was very angry so she took away Echos voice and said she can only repeat what people say.
Echo and all the children felt very sad that she had lost her voice and all she could do now was wonder through the woods hoping for a miracle to happen.
