As an autistic teenager, I struggled to find books written for autistic girls.

So I decided to create the type of workbook that I wished existed.

"The Spectrum Girl's Survival Toolkit is an essential and practical workbook with a wealth of information, strategies, and resources for young women with autism.” - Dr. Tony Lloyd, CEO, ADHD Foundation

"I wish I’d had The Spectrum Girl’s Survival Toolkit when I was a teenager navigating the neurodiverse world. "- Samantha Craft, International Trainer, DEI Manager, Author of Everyday Aspergers and Contributing Author to Spectrum Women: Walking to the Beat of Autism

A companion to the bestseller The Spectrum Girl's Survival Guide, this essential toolkit workbook for teen autistic girls gives you the coping strategies needed to overcome the challenges that may be holding you back.

Written by an autistic teenager

"I bought Siena's first book for my recently diagnosed daughter which was / is brilliant and serves as a huge relief for me as a parent knowing she's got a go to book to help her. When Siena said that she was writing this book to accompany it I was so excited and I've not been disappointed.

My daughter accepts her diagnosis but doesn't want to talk about it yet. This, however, is the first book on autism she will allow to remain in her room and wants to work through. When she heard that it had hints, tips and activities to help with areas she finds tricky and is most worried about (with going to secondary school in September) she was very interested. Each part explains and explores different areas that ASD girls may experience and has spaces to work through the various activities in their own time. It's a thick book with clear and accessible writing; simple but cute pictures. As parents we feel that this is a huge break through for us all... thank you!"

About The Author


Siena Castellon (she/her) is an 18-year old neurodiversity advocate and author from Ireland who lives in the United Kingdom. She is autistic, dyslexic, dyspraxic and has ADHD. When she was 13, she discovered that online resources were focused on supporting the parents of children with special educational needs (SEN). Siena decided to address this by creating, a website that supports SEN students.

Most recently, Siena launched Neurodiversity Celebration Week, an international campaign that aims to challenge negative perceptions and stereotypes about autism and learning differences by encouraging schools to flip the narrative from focusing on the challenges of being neurodivergent to focusing on strengths and talents. Over 760 schools and over half a million students from around the world took part in 2020.

Siena is also the bestselling author of “The Spectrum Girl’s Survival Guide: How To Grow Up Awesome and Autistic” and "The Spectrum Girl's Survival Toolkit: The Workbook for Autistic Girls." When she found that most books were written for autistic boys and that there were no books aimed at supporting the unique challenges faced by autistic teen girls, Siena decided to change this. In April 2020, she launched a successful crowdfunding campaign to raise funds to donate a book to every state school for girls in the United Kingdom.
