Puerto Ricans, a N.Y.U. Professor's family and the city of New York are the vital elements described here by a writer who knows how to impart information without impeding her story. The five Lawrences move from Connecticut to Manhattan where Grannie Bogardus lives- in an old house with historical connections near St. Mark's in the Bouwerie. Near by live the Perez family, with six children. In time there is the Lawrence's and the Perez' mutual acquaintance- helped by the fun of doing things together and Grannie Bogardus' decision to repair the Perez house- hindered by eleven year old Avis' difficulty accepting foreigners and fifteen year old Alfredo's unfortunate experience with drug smugglers. And as complements to a warm story are trips to the tulip festival and the Dutch Klompen Folk Dances, the Cloisters, and Grannie's stories about the city when she was a girl along with much of its Dutch history. Fine regional reading.
