does anyone know what a good theme for the book crossing montana would be? below is a summary......10 pts. thank you!!! Grade 7-10 Callie's mother rushes the 10th grader and her 9-year-old brother, Stink, from their home in Washington to Idaho because their grandfather is missing. From clues he had given her in the past and seeing that his favorite fishing gear is gone, Callie assumes he has headed to a special spot on the Gallatin River, and she decides to search for him, in secret. She takes her mother's car and some money and begins her journey to Montana, only to discover that Stink has stowed away in the trunk. Ultimately, she finds her grandfather, drunk and unruly, trying to swipe a prime fishing spot on the river. Her romantic interest, Raf, shows up in the nick of time to rescue her and encourages her to return home. Told in flashbacks, the story involves a parallel plot about Callie's father, who left on a trip across Montana when she was small and then died in an automobile crash. This is as much a book about Callie seeking answers and closure over his absence and death as it is a quest for her missing grandfather. Characters are adequately drawn but some elements of the plot seem implausible, created simply to get Callie to Montana to learn the truth about her father-his "accident" was actually suicide.
