The perfect trip turns into a nightmare . . . Amber Pierce thought she'd planned the perfect family vacation. Seeking to mend the rift with her daughter, she books a camping retreat in the breathtaking Cascades . . . a trip that includes her ex-husband and his new wife. But hours into their first hike, the group takes a wrong turn. Days later, they're lost, hungry, dehydrated, and hope is fading. Amber is no quitter. Not in her job as a teacher and not for her family. She's always dealing with difficult people. Compared to a classroom, this will be a piece of cake. She'll lead everyone to safety. Or die trying. Or so she thinks. When one person goes missing and another falls victim to a mysterious accident, Amber soon discovers she's in over her head. Who is sabotaging their trip? And can she stop them before it's too late?
