Does Isabel rescue Ruth in the book chains?

Yes, Isabel does rescue Ruth in the book "Chains" by Laurie Halse Anderson.

Here's how it happens:

* Isabel and Ruth are both enslaved by the Lockton family.

* Ruth is sold to a different family, and Isabel is determined to find her.

* With the help of Curzon, a free Black man, and the support of the community, Isabel finds Ruth and helps her escape to freedom.

While Isabel doesn't physically fight anyone to get Ruth back, her actions, courage, and determination are key to Ruth's rescue.
