Keep a little secret

When a teaching position opens up in Oklahoma, Charlotte Tucker jumps at the opportunity to take a room on John Grant's ranch in Sawyer to begin her new career. She soon befriends Owen and Hannah Wallace, a brother and sister who have come from Colorado following the death of their mother. Abandoned at an early age by a father they never knew, they are set on revenge against the man who left them -- a man they believe is John Grant.
