Reddit reviews Generation X: Crossroads

There was a Generation X novel I remember reading years ago, I think before that movie came out but unsure. It said exactly your theory as fact by having a college fraternity for mutants. Their symbol was a 6 fingered hand representing a mutant whose mutation was an extra finger and a lot of mental physical disorders who was beaten to death for being a mutant I think.

And all the members of that frat were mutants or mutant supporters, but the mutants had powers like "I can make my drinks cold. That guy can find lost things sometimes if he's close to the person. That guy can talk to dogs but can't control them, just talk."

Edit: I ain't paying 30 bucks for it but this one I think. https://www.amazon.com/Generation-Crossroads-J-Steven-York/dp/0425166317
