This Book Is Gay By Juno Dawson

The bestselling young adult non-fiction book on sexuality and gender!
Lesbian. Gay. Bisexual. Transgender. Queer. Straight. Curious. This book is for everyone, regardless of gender or sexual preference. This book is for anyone who's ever dared to wonder. This book is for YOU.
There's a long-running joke that, after "coming out," a lesbian, gay guy, bisexual, or trans person should receive a membership card and instruction manual. THIS IS THAT INSTRUCTION MANUAL. You're welcome.
