Piper's life is turned upside down when her family moves into a shelter in a whole new city. She misses her house, her friends, and her privacy, and she hates being labeled the homeless girl at her new school. But the shelter offers new friendships with the girls in Firefly Girls Troop 423 and a sweet street dog named Baby. So when Baby's person goes missing, Piper knows she has to help. But helping means finding the courage to trust herself and her new friends, before Baby gets taken away for good.
