When Alyssa refuses to pick a side, and instead tries to search for the mysterious "Knave" from the mysterious messages someone known only as "the Smoke" keeps sending her, every choice she makes drags her and the haunted - and haunting - Jack Knightly deeper into the strange world of the witch queens of the Twilight Chessboard.

And both Alyssa and the Knave are running out of time...
