The World Of Ptavvs by Larry Niven. Paperback edition published by Sphere in 1971.
Larry Greenberg's telepathic tendencies had been trained and developed to a critical level.

But when Larry's mind is taken over by an alien force, he has to fight to retain his sanity - and divert a disaster that threatens all mankind.

A little worn externally but good general condition. Pages yellowed but clean and securely bound. Some creasing and wear to the covers and spine. A scarce vintage copy.
