You guys seem pretty well versed in this sort of thing, so I though that I would see if you could help me find a book. Here is what I can remember:
It is a sci-fi genre and it deals with telepaths (perhaps Psion abilities as well but I am not sure). It seems like there are two opposing groups of them and they are gathering more around them. One detail that I remember is that psychics in this story tended to either be alchoholic or drug users or abuse their children or something because of the low grade signals that they were picking up driving them crazy. I think that the cover had a bald person with a halo or something radiating from their head and it may have ended with the “good guys” creating some sort of a psychic network (mass mind?). I think that I would have read it in the mid 90s
Ring any bells?
