Wow my futuristic dystopia is completely the opposite of Samantha's. We already talked about this in another thread but I will talk about it more here lol. Race doesn't matter at all, because the way I see it more people will be biracial in the future. No one is labeled white or black, but pale, tan, caramel, light-skinned, or dark-skinned, if color is even mentioned at all. My MC has curly dark hair, light brown skin, and blue eyes. But the nation is divided into so-called normal towns and walled Gay Communities. Anyone who is LGBT is labed gay and banned for life. My MC is a 17 year old from a normal town who is secretly a lesbian, and joins the revolution to end the divide between gay and straight. I never pinpoint a specific time frame, but I mention The Divide was created during Civil War 2, followed by a Great Oil Shortage, and people mention that their grandparents were living in walled Gay Communities so it's been at least 2 generations since the divide was created, and it's been 20 years since the Normal Verification Test was made mandatory. (I will go into more detail about what exactly that test involves in the next book.)
I think your idea is great too! I hope your vision of at least the LGBT future is more accurate.
My book will be published next month and I can't wait . . . it's book 1 of a 2 book series.
