Rima loves to ride horses alongside her abuela and Las Mambisas, the fierce women veterans who fought during Cuba's wars for independence. Feminists from many backgrounds have gathered in voting clubs to demand suffrage and equality for women, but not everybody wants equality for all -- especially not for someone like Rima. In 1920s Cuba, illegitimate children like her are bullied and shunned. Rima dreams of a day when she is free from fear and shame, the way she feels when she's riding with Las Mambisas. As she seeks her way, Rima forges unexpected friendships with others who long for freedom, especially a handsome young artist named Maceo. Through turbulent times, hope soars, and with it... love.
