Sisters Anna and Jennie live in a historic bungalow on the Chicago River. They're tethered to a disquieting past, and with nowhere else to go, nothing can part them from their family home. Not the maddening creaks and disembodied voices that rattle the old walls. Not the inexplicable drownings in the area, or the increasing number of bodies that float by Anna's window.

To stave off loneliness, Anna has a podcast, spinning ghostly tales of Chicago's tragic history. But when Anna captures the attention of an ardent male listener, she awakens to the possibilities of a world outside.

As their relationship grows, so do Jennie's fears. More and more people are going missing in the river. And then two detectives come calling.

They're looking for a link between the mysteries of the river and what's housed on the bank. Even Anna and Jennie don't understand how dreadful it is--and still can be--when the truth about their unsettled lives begins to surface.
