The cover art features a retro-look design with gold Victorian-style lettering on a dark background. This is flanked by poppies in black silhouette. The poppy has long been associated with sleep and forgetfulness. Suitable, therefore, for the mysterious, ghostly quality of the story. The poppy symbolism is also reflective of the sinister 'time-slip' element experienced by the author of the journal.
Also included in the texture of the background is a motif of antique, and slightly damaged Chantilly lace. This refers to the heroine’s association with that region of France once famed for its lace-making. The magnificent chateau of Chantilly, meanwhile, also forms the setting for a good part of Sophie's life as Baronne de Feuchères.
A sinuous gold frame is mounted close to the margins adding to the luxurious feel. And the author’s name is picked out in contrasting scarlet at the foot of the design.
