Twins Cam and Cass have never known their parents. They've been told their mother died, and Cass is certain their father abandoned them. Cam isn't so sure. He wants to prove her wrong; he must .

Cam's wish is soon granted in the form of a glistening, golden sign with elaborate flourishes that reads: The Hotel Between . With doors that open to countries all over the world, magical trollies, charmed corridors that can be altered on a whim, stone elephants that come to life, sweets made from rocks; everything is possible in the Hotel. Cam has a hunch his father is somehow connected to this magical place, and may even be lost within its hidden halls.

Every journey has its risks, and The Hotel Between is full of dangerous secrets. If Cam's not careful, his stay may be over before his vacation has even started.
