Set in Texas, two sisters, Diane is eighteen and Katie is twelve, live with their strict, military father. He's always been a difficult man to live with, but things have become much worse for the girls ever since his wife died. Katie misses her mom terribly, so much so, that when things get too difficult for her, she lies under her bed and speaks to her mother, hoping she will come to her and tell her what to do with her life. When Diane makes a decision to move to Mexico with her boyfriend, she talks Katie into going with them, but on the way Katie decides this might not be a good decision.
Katie is a deep thinker which helps her to understand why people do the things they do.
