I’m not a cartography nerd but I do appreciate a well-crafted map. Nell Young, the heroine of this book, is an extremely Nancy Drew type who can’t leave well enough alone; her discovery of a seemingly worthless old map upends her life and suddenly she’s running from a shadowy cabal of creepy map enthusiasts. Her investigations uncover deep secrets in her parents’ past, and uses the idea of copyright traps as a jumping-off point. I thought the plot got a little forced here and there, and the writing was a little amateurish in places, but I loved the ideas.
