I received a digital Advanced Readers Copy from Netgalley and all opinions are my own.
I found this book really interesting! It covers a lot of different people though I wish there were some Aromantic People covered and more Asexual people talked about. (There is an A in LGBTQIA for a reason.)
I learnt a lot I didn't already know plus there seemed to be a wide spread of more and lesser know figures as well as ones from different times throughout history. 
This book is great if you want a base to do more research on or if you want to learn the basics about these important LGBTQIA+ icons.
