In their small town, everyone believes that meeting chimney sweep Clare Ridley brings good luck—her friend Ashley, in particular, is convinced of this. Clare does indeed bring good luck when she pulls architect Josh Harding—with whom Clare had secretly been in love before he moved to New York—off the street just in the nick of time. He has now returned to help his widowed aunt Jessica. He asks Clare’s father, Daniel, who runs a small chimney and heating company, for his professional expertise regarding his aunt’s historic home. Clare has little desire to see Josh again, but her father needs the job.
