On a Darkling Plain — Maggie Wheeler

So much for a summer of light emotional entertainment. In the month marking fifty years since the inundation of the St. Lawrence Seaway, the remains of a young man gone missing during the Project days surface near Old Iroquois and stir up a hornet's nest on both sides of the river. While dodging a cold-blooded killer, her approaching fiftieth birthday, and emotional commitment to Inspector Jerry Strauss, Farran Mackenzie faces reconnecting with the daughter she gave up twenty-six years beforeâ€"and the dark secret that drove them apart in the first place.
