When her mother dies, fifteen-year-old Mari is desperate to avoid being caught up in the foster system....again. And to complicate matters, she is now the only one who can take care of her super-smart and on-the-spectrum nine-year-old stepbrother, Conor. Is there anyone Mari can trust to help them? Certainly not her mother's current boyfriend, Dennis. Not the doctors or her teachers, who would be obliged to call in social services.
