The Broken Lands: 08/11/17
The Broken Lands by Kate Milford is the prequel to The Boneshaker. It's set in New York City as the five boroughs are coming together into the city we now know.
The story introduces a variety of characters, each who will come together to protect the newly formed city during a crossroads battle. There are numerous points of view, the soon to be heroes, the gathering villains, and their cohorts.
But it's complex and tangled. The Boneshaker worked because it was set in a small, out of the way town, with a single road in and a history with an old ghost town. It is a quintessential road not taken story.
In terms of the road trip genre, New York is one of the terminals for road trips: either being the starting point, or the ending point. New York isn't a city that can contain a road trip. A crossroads battle in the middle of a metropolis, even one that at the time was more than one city being in the process of becoming a single city, just doesn't work.
