The Last Doctor

A backpack full of antibiotics is worth more than gold in a world where ninety percent of humanity lies buried. Naomi Falk, a former ER physician, walks the empty roads of the Midwest alone, carrying the last real medicine for hundreds of miles toward a settlement desperate for a doctor. But when she saves a dying stranger and accepts his protection, she discovers too late that his loyalty was purchased by the very raiders hunting her. Now Naomi must decide whether trust is a luxury she can afford—or the only thing keeping her alive.
