I have not actually read this book, but had looked up the plot with the intention of eventually reading it; unfortunately, I forgot the title.
The book takes place in the future, I believe on another planet where colonists have recently settled. However, there was a disease or something else in the environment of the planet that resulted in everyone's thoughts becoming uncontrollably public. However, a boy accidentally discovers a lone patch of silence somehow generated by a girl. The fact that he discovered silence was unacceptable, and as such he had to escape from his community. Furthermore, I think his community was exclusively male- the females might have been wiped out by the same thing that caused the forced telepathy.
I'm not entirely sure when this could have been written, but I feel that it is a more modern book.
