Autism Social Skills Textbook for Parents

I need a comprehensive textbook designed for parents to teach social interaction skills to autistic pre-teens (ages 11-13). The primary focus is on teaching social interaction.

The textbook should incorporate a variety of engaging activities, including:
- Group activities
- Role-playing exercises
- One-on-one interactions

Ideal skills and experience:
- Background in child psychology or special education
- Experience working with autistic children
- Strong writing and organizational skills
- Ability to develop engaging and educational activities
