So much has changed in Tilly's life over the past few months! She learned that, like the rest of her family, she could travel through books, found her mother trapped in one, and even found out who her father was. Now the Christmas holidays await her, and not just anywhere, but in Paris itself, but Tilly does not yet know what this trip will bring for her and Oscar. Very soon, the children will have to discover a new area for travel - wild and wonderful fairy tales, face a new enemy of book travels and unravel several strange and even dangerous mysteries: what kind of miracles are happening with fairy tales these days, who is stealing book magic from them, and most importantly - why? ?
