It is 1855 in Manhattan and Maria Peters is 13 years old. The African-American girl wants nothing more than to take part in the local abolitionist meetings, but getting into fights in the schoolyard and failing her class sewing project lead Mama to believe she isn’t mature enough to attend. But when the new girl at school turns out to be a runaway slave, Maria has a chance to show her family that her commitment to freedom is serious. Set against the backdrop of a New York City that was in the process of evicting free blacks and Irish and German immigrant families from the area that became Central Park, this straightforward series opener aims for the cozy feel of the Little House or All-of-a-Kind Family books, rich with details of Maria’s home and school life. Unfortunately, Hansen misses that mark with occasionally didactic dialogue and slow pacing. Still, young readers will find the setting fascinating, and this will pair well with Tonya Bolden’s nonfiction Maritcha: A Nineteenth-Century American Girl (2005). (Historical fiction. 9-12)
