The Graveyard Book meets The Night Circus in this ghostly tale about two friends, one murder mystery, and a world of intrigue.

   But then disaster strikes. Silvie goes missing--and it's up to Ema to find her. Now she must gather the courage to hunt the city, find her friend, and uncover the secrets of the one clue Silvie left as to where she might be--inside the mysterious Midnight Guild...
