The Pool sisters have gone into business together: a down-home if unequal P.I. enterprise. That is, until Lila is tipped off to an explosive piece of news. An old friend of their Aunt Ruth's --- a lawyer and academic who’d committed suicide years ago --- believes that Ruth was murdered. Prior to her death, Ruth had represented a chemist who’d been struggling to patent a dangerous synthetic opioid. But once the client, Travis Nutt, was poised to lose, he went rogue and unleashed the adulterant as a street drug with the power of cartel funding behind him. Can the twins now bring this cult-like billionaire to justice?

Jane Pool likes her safe, suburban existence just fine, but she remains haunted by her past: her mercurial, absent mother, her parents’ secrets, and the act of violence that transformed her life. When her estranged twin, Lila, makes contact, claiming to know where their mother is and why she left all those years ago, Jane agrees to join her, desperate for answers and the chance to reconnect with the only person who really knew her true self. Yet as the hunt becomes treacherous and pulls the two women to the earth’s distant corners, they find themselves up against their mother’s subterfuge and the darkness that always stalked their family. Now Jane stands to lose the life she’s made for the one that has been impossible to escape.

One night, three people --- a couple and their child --- hurry out the door of their modest house in upstate New York, but it’s too late for them. As the opening scene of BROKEN RIVER unfolds, a spectral presence seems to be watching with cold and mysterious interest. Soon the house lies abandoned, and years later a new family moves in. Karl, Eleanor and their daughter, Irina, arrive from New York City in the wake of Karl’s infidelity to start anew. Twelve-year-old Irina becomes obsessed with the brutal murders that occurred in the house years earlier. And, secretly, so does her mother.
