Hoopi Shoopi Donna

Growing up in a small New England town, 14 year-old Donna Milewski had all she needed: a grandmother, Babci, whose fragrant cooking filled their home...her mother, Helen, who lovingly stitched outfits...and Adam, the most wonderful father a daughter could imagine, who dreamed she could one day lead an all-girl polka band.
Then came Betty, a tiny and adorable five-year-old, sent from Poland by Adam's destitute brother. Bringing with her only a rubber doll's leg and her old-world charm, Betty became the little sister Donna never had -- and a threat to her father's love. During a long and painful rift, a dance of betrayal and hurt, Donna must look to her beloved polka music for the key to healing.
