Ten-year-old Min has had a long history of foster care since she was abandoned at age three. Now, let go by yet another foster family, Min continues to build a protective wall around herself. Her newest caregiver, a former Children's Aid doctor, sees past Min's hardened shell and tries to find a way to reach her...and does, finally, by taking in a sick, neglected dog that has escaped from a puppy mill. While watching the dog recover and open its heart to its new owners, Min comes out of her own shell.

Readers will rejoice as Min opens her heart and allows herself to be a part of a loving family, to make friends and to finally stand up to the taunts of a bully, whose hurtful words have contributed to her lack of self-esteem.
