The Santaroga Barrier by Frank Herbert. Paperback edition published by New English Library in 1974 (reprint).

Strange things are happening in the seemingly peaceful and prosperous farm community of Santaroga, a place where no one ever moves out of town, there is no juvenile delinquency or crime, and no cheese, wine, beer, or produce from the outside can be sold. 

Very good general condition. Pages are yellowed but clean and tightly bound. A little creasing and wear to the covers and spine.

Thanks for looking. If you decide to buy, please complete checkout for payment instructions.
