Two's company. Three's a.temptation. A hike to the bottom of the Grand Canyon isn't supposed to be an erotic adventure. Dr. 'Gabe' Gabriel is more than a little turned on by the young couple he meets on the trail but he doesn't do threesomes anymore. Someone always gets hurt. Not everything is what is seems and despite a close encounter of the intimate kind, Uriah and Diane are here for a reason. Leaving any possibility of romance behind, they head to the inner canyon and the isolation they need. Reunited by chance, the threesome's mutual attraction is hotter than the scorching Arizona desert in the middle of August. Still, secrets have a way of chilling the strongest passion, especially a secret holding a gun, and a heart cold enough to pull the trigger.
