When I first started this book I thought it was going to be a five-star read and one of my new favorite books. After finishing it, I have so many unanswered questions from all the plot holes.
Spoiler Why didn't Agloe disappear when Wally made Nell tear up the gas station map if they weren't sure there was another one?
What exactly was Wally trying to do by scanning the gas station map into his Haberson map?
Why didn't he draw his own map to Agloe?
How did Nell even move the town? 
Also, Swann didn't deserve to die and his death was lame and pointless. 
Despite this books shortcomings, I did enjoy it, the few plot twists it holds, and the ending (the last chapter at least).
