The first of the Psionicist Guild books. It is history textbook from the future. It is four novella of the initial inner circle of the founders of the modern Psionicist Guild. This not a children’s book, since the SEX word is used and people date, have sex and get married, some parents will object. PG-13 (ish) is probably a fair label. I don’t think it gets and R unless I missed and F bomb in my memory.
