Kit Holloway and Tyler McCord have been friends since childhood, in love since high school. Now they're planning a big wedding and an exciting future together as river guides taking rafters through the wild rapids of the Grand Canyon. But Kit's father and Tyler's mother have plans too, plans that open a yawning canyon of differences between Kit and Tyler and shatter their future together. Their lives go in totally different directions until a plane crash forces them into a tense and temporary reunion and a dangerous rescue on the river. Their feelings for each other resurface, but are those tempestuous feelings enough to break through that canyon-deep barrier that still stands between them?
