Testimony by Anita Shreve

As an Anita Shreve reader I was not disappointed with this novel.
Three senior student boys and a younger girl from a private school have been filmed in sexual activities. The reader is made to think and consider all possibilities.
Who is responsible for the life changing event?
Would the outcome have been different if certain characters had acted differently?
Why would one young man's character change apparently overnight?
Was the girl, although younger, the initiator of the whole thing?
This book held my interest from beginning to end. A must read.
