Reach for this book when your child is facing a major life transition, like moving to a new city or starting a new school, and needs a reminder that they are not alone in their uncertainty. It is particularly effective for siblings who are struggling to find a balance between their shared identity and their individual strengths. The story follows identical twins Mal and Colm as they discover their new apartment building holds a ghostly secret: a hidden thirteenth floor that exists in a parallel dimension. While the plot is a fast paced supernatural mystery, the heart of the story explores how fear can be managed through teamwork and how curiosity can lead to unexpected bravery. It is perfectly suited for children aged 8 to 12 who enjoy a bit of a chill but still want a story grounded in family love. Parents will appreciate how the boys must set aside their rivalry to solve puzzles and protect their family, making it an excellent bridge for conversations about cooperation and adjusting to change.
Themes of loneliness and the difficulty of leaving one's old life behind.
Atmospheric ghost encounters and a creepy parallel dimension.
The book deals with ghosts and the 'half-living,' treating death with a metaphorical, slightly eerie lens rather than a grim or religious one. The resolution is hopeful, emphasizing the continuity of family and the importance of memory.
A 10-year-old middle child or twin who feels they are always seen as part of a pair and wants to prove their individual worth, while also being a fan of spooky 'escape room' style puzzles.
Read cold. The spooky elements are atmospheric but generally safe for the middle-grade audience. Parents of sensitive children might want to preview the scenes involving the 'shadow' versions of the characters. A parent might notice their child retreating into video games or books after a move, or perhaps overhearing constant bickering between siblings who are usually close.
Younger readers (8-9) will focus on the 'cool' factor of the secret floor and the monsters. Older readers (11-12) will better grasp the nuances of the twins' identity struggle and the historical mystery of the building.
Unlike many haunted house stories, this uses an urban, high-rise setting and the unique psychology of identical twins to drive the plot, blending modern city life with classic gothic mystery.
After moving into the Brunhild apartments in Chicago, twins Mal and Colm discover a hidden thirteenth floor accessible only via a mysterious button. This floor exists in a shadow dimension where time stands still and ghosts reside. To save themselves and their new home, the twins must navigate a series of supernatural challenges, outsmart a malevolent force, and solve the mystery of the building's past.
