From Tina

Tina's older brother Seb has mysteriously disappeared from their grandparents' house in Toronto. The same house their grandparents died in. The same house they inherited that same year, from the grandparents who'd raised them. The same house that had contained mysterious noises and nooks their entire childhood.

Now, Tina is taking a gap year to search the house and the city for any clues to where her brother might be, and what happened to him. Little does she know, there's a lot more to this mystery. Little does she know, there's a lot more to their house than some sounds and odd corners. It could just be that the house itself, and all that's hidden in its basement, are at the center of not only her brother's disappearance, but a whole other world of possibilities.
