The Mark of Abena

When Kate pissed off her friend Abena, she mysteriously disappeared in an abandoned house, never to be seen again. Ten years later, thirteen year old Conner Tran goes into the same house, now haunted. There, he sees many things that he shouldn't be seen. He comes out, and suddenly, he's being targeted, by someone. Now on the run, he will have to defeat Abena, with the help of Kate, that girl who pissed the hell out of her former friend. Will they actually survive to the end of the hall, or will they end up with the mark of Abena?
