FBI special agent Michael "Gray" Grayson had an agenda…and it didn't include protecting a beautiful loner in the wilds of Colorado who probably knew more than she was sharing. Still, the fear in Mariah Shore's amber eyes after he rescued her from the clutches of a terrorist mastermind seemed all too real. And since Gray wasn't about to watch another person suffer while he felt helpless to stop it, Mariah was now his unwilling partner in uncovering a deadly plot. Before long, looking for answers and hiding out in the cold, tight canyons of the Colorado mountains turned their investigation much more intimate. And believing in Mariah's claims of innocence gave Gray that much more to lose.
