Sojourner's Ridge is a complex mystery about Sarah, a fourteen-year-old girl and her six-year-old brother, Lenny, from Arkansas and a successful writer, Julia, from New York. They are complete strangers, yet they have one thing in common: both sets of parents died on the same day at the exact same time. Sarah knows what happened; but fearing the authorities, she must keep it a secret. Now orphaned, Sarah must find a way to survive and take care of Lenny.
 
Julia is determined to find out who killed her parents and chases endless clues, until one day she discovers what Sarah knows. But, if Julia tells the police, it could change their lives forever. Is that a burden she's willing to carry? Or is it now her secret as well?
