Aaron Fisher writes in "Silent No More" that Dottie Sandusky asked her husband to fix a table upstairs. He says Jerry Sandusky told her he was fixing an air hockey table and she dropped the subject.
The Associated Press bought an early copy of the book, being published next week.
Dottie Sandusky maintains she never saw her husband behave inappropriately with children.
Fisher was described in court records as Victim 1. He spoke out on television Friday.
Jerry Sandusky was convicted in June of abusing 10 boys, including Fisher. He says he's innocent.
