Sam is a loner who prefers to call the open road his home. His life is carefree-a constant change of scenery and zero commitments, just the way he and his pitbull passenger like it. Pearl is a photographer who has just accepted the feature assignment of her dreams. Her subjects-Vermont's oldest covered bridges-have none of the baggage humans bring. But lately, Pearl's nights have been consumed by a darker undertaking: outrunning the faceless threat that haunts her dreams. Each passing mile brings her closer to the truth behind the nightmares.

Sam and Pearl have little in common-he needs an escape plan and she's desperate for closure-but then their paths converge to lead them to the same realization . . . that sometimes home is much closer than it seems.
