Twelve-year-old Sarojini's best friend, Amir, might not be her best friend any more. Ever since Amir moved out of the basti and started going to a posh private school, it seems like he and Sarojini have nothing in common. Then Sarojini finds out about the Right to Education, a law that might help her get a free seat at Amir's school – or, better yet, convince him to come back to a new and improved version of the government school they went to together. As she struggles to keep her best friend, Sarojini gets help from some unexpected characters, including Deepti, a feisty classmate who lives at a construction site; Vimala Madam, a human rights lawyer who might also be an evil genius; and Mrs. Sarojini Naidu, a long-dead freedom fighter who becomes Sarojini's secret pen pal. Told through letters to Mrs. Naidu, this is the story of how Sarojini learns to fight – for her friendship, her family, and her future.
