Kimberly King, a kindergarten teacher, thought she had done a good job of discussing appropriate and inappropriate touch with her kids. However, when her 5-year-old son, Zack, went to the neighbor's house for a sleepover, he was not really prepared for what happened. Zack ended up being pressured by his best friend to engage in inappropriate behavior.
While Zack found creative ways to resist cooperating, he was deeply effected by the event. This book is co-written by Zack and his mom as a way to help other kids learn from Zack's experience.
It's a wonderful resource for helping discuss the difference between people who are behaving appropriately ("green flag people") and those who aren't ("red flag people"). Children are given examples of how they might be bribed or threatened along with ideas for how to tell someone.
