I remember reading the first volume of a series of books, and would like to find the series again to read the end. The main character was a child, named Jack, and his whole family had paranormal abilities. Jack has something wrong with him physically, so he is in bed most of the time, but he can sense that his siblings and cousins are using their powers to suck life power from people through their chakra’s to gain power. I’m afraid that’s all I know. The series must be at least 17 years old, because that is when I read the first book from the library. Many thanks!
