The Day the Falls Stood Still by Cathy Marie Buchanan
My rating: 5 of 5 stars
Summary: Tom Cole, the grandson of a legendary local hero, has inherited an uncanny knack for reading the Niagara River's whims and performing daring feats of rescue at the mighty falls. And like the tumultuous meeting of the cataract's waters with the rocks below, a chance encounter between Tom and 17-year-old Bess Heath has an explosive effect. When they first meet on a trolley platform, Bess immediately recognizes the chemistry between them, and the feeling is mutual.
