The other half of happy

Twelve-year-old Quijana is a biracial girl, desperately trying to understand the changes that are going on in her life; her mother rarely gets home before bedtime, her father suddenly seems to be trying to get in touch with his Guatemalan roots (even though he never bothered to teach Quijana Spanish), she is about to start seventh grade in the Texas town where they live and she is worried about fitting in--and Quijana suspects that her parents are keeping secrets, because she is sure there is something wrong with her little brother, Memito, who is becoming increasingly hard to reach.
