Beah cannot help but wonder what lies beyond her earthly existence. For quite some time, she has been frightened by the unexplainable opening and closing of doors, the sounds of footsteps and muffled voices, and the echoes of a child's soft crying while home alone in the Massachusetts Victorian home she shares with her husband. Because no one else ever sees or hears anything unusual, Beah invents logical explanations, for such things just do not happen or so she thinks.

One day while working on the old house, Beah unwittingly loosens a baseboard and unearths an antique pocket watch. Unaware of its mystical powers, Beah eventually falls asleep on the floor, only to awaken as a child in the Victorian era who is happily interacting with the house's original occupants. But when she voyages into the past a second time, Beah is metamorphosed into a teenager who must sail dangerous oceans disguised as a cabin boy. While she faces death under the sea, a murderer pursues her through time. As Beah precariously dangles between the past and present, she must uncover the truth, before it is too late.

Voyages from Main Street is the tale of a woman's perilous journey through time as she desperately searches for answers and attempts to outrun a determined killer.
