Jenny Weston and her mother, Dora, have been receiving strange midnight visits. The town of Bear Falls, Michigan, has its own elusive and highly secretive poet, Emily Sutton, who has lived her life cloistered away with her sister in a house at the edge of Pewee Swamp. But now, Emily has started leaving scraps of poetry in Dora’s little free library, and Dora makes it her mission to befriend the sheltered woman.

Meanwhile Zoe Zola—almost famous author, little person, and the Westons’ quirky next-door neighbor—is hard at work on a new book, this one about the inner life of Emily Dickinson. And once again, Zoe’s literary work starts making uncanny connections with the events in her own world as Emily Sutton reemerges into society. But Zoe begins to suspect things aren’t anywhere near normal at Emily’s swamp house or in the lives of the people she claims have abandoned her—until looking further into the poet’s half-truths leads Zoe and Jenny to a horrible murder.

The chaos surrounding the ensuing investigation grows even more hectic with Emily’s increasingly erratic behavior, the arrival of a young woman searching for her missing poet uncle, and yet another betrayal in Jenny’s love life.

And only poetry can set the truth free.
