The cartographers: a novel

"What is the purpose of a map? Nell Young's whole life and greatest passion is cartography. Her father, Dr. Daniel Young, is a legend in the field and Nell's personal hero. But she hasn't seen or spoken to him ever since he cruelly fired her and destroyed her reputation after an argument over an old, cheap gas station highway map. But when Dr. Young is found dead in his office at the New York Public Library, with the very same seemingly worthless map hidden in his desk, Nell can't resist investigating. To her surprise, she soon discovers that the map is incredibly valuable and exceedingly rare. In fact, she may now have the only copy left in existence ... because a mysterious collector has been hunting down and destroying every last one--along with anyone who gets in the way. But why? To answer that question, Nell embarks on a dangerous journey to reveal a dark family secret and discovers the true power that lies in maps"--
