Lean, atmospheric, and unexpectedly tender. The partnership between Mara and Eli gives the mystery warmth, and the civic details feel lived-in rather than researched to death. Not perfect pacing, but I kept turning pages.
After her father's death, surveyor Mara Kincaid returns to Myford, Ohio, a town stitched around the shuttered Pierce & Sons Foundry. In his garage she finds a dented flat-file of township plats marked with red Xs and pencil notes like don't trust Ashhollow. As the foundry's siren starts wailing at odd hours and someone repaints the town boundary in fresh white at night, Mara realizes the maps point to a secret the residents have chosen to unsee.
With teen map-nerd Eli Ramos and retired union steward Len Hart, she follows the Xs from the covered bridge to the VFW's Blue Room, chasing a 1968 charter revision buried during a flood. Their search uncovers an unofficial landfill beneath Myford High's football field and a paper-company note that could erase the town. When a standoff at the No. 7 water tower turns dangerous, Mara must choose whether to redraw Myford's borders or save the people within them, knowing lines on paper can cut as sharply as steel.
