Happy Hollow

Happy Hollow is a facility full of children who are lost and confused and, most of all, totally devoid of their past. They have no memories. None of them know why they are here, and strange things keep happening to the children. A girl speaks to people through the toilets, a boy--known as a screamer--recently had his teeth go black before he bashed his own head in. When the main character is put into The Black Box, he starts to remember his past, and everything changes.
