Shut Up! — Marilyn Reynolds

When their mother is called to Iraq with her National Guard Unit, 17-year-old Mario Barajas and his 10-year-old brother, Eddie, are sent to live with their Aunt Carmen. Soon after the boys move in, their aunt's boyfriend, Denton, begins spending more and more time at Carmen's, particularly with Eddie. When Mario notices that his little brother is laughing less and behaving rather strangely, he soon discovers the sexual abuse that Eddie has been suffering at the hands of Denton. With their mother miles away, their aunt's boyfriend threatening to split the boys up into different foster homes, and his brother refusing to tell anyone else the truth, Mario must do whatever he can to keep his brother safe. This is a gripping and moralizing tale of trust, betrayal, and secrets that should never be kept.
