To help save her family's floundering Colorado bookstore, Starlit Bookshop, newly minted Ph.D. Emma Starrs agrees to plan a mystery-themed dinner party for her wealthy, well-connected high school classmate Tabitha Baxter. It's a delightful evening of cocktails and conjecture until Tabitha's husband, Tip--hosting the affair in the guise of Edgar Allan Poe's detective C. Auguste Dupin--winds up murdered.

In a heartbeat, Emma and her aunt Nora, a famous mystery writer, become suspects. Emma is sure the party's over for Starlit events, until celebrated author Calliope Nightfall, whose gothic sensibilities are intrigued by the circumstances, implores the bookseller to create a Poe-themed launch event for her latest tome. Throwing a bash to die for while searching for additional clues is already enough to drive Emma stark raven mad, but another shocking crime soon reveals that Silvercrest has not yet reached the final chapter of the puzzling case.

Someone in this charming artistic community has murder on the mind, and if Emma cannot outwit the killer, she and her beloved aunt will land behind bars, to walk free nevermore.
