Girl: Your parent(s) die. Filled with grief and anger, you are sent to live with your uncle/grandma/some other relative in a tiny town in the middle of a ridiculously dense forest. You are told never to go into the forest at night, and especially not alone. But filled with rebellion from your parent(s) death, you go in there anyways. You run into a man, a man who has the ability to turn into a wolf. He kidnaps you, and shows you his pack. Your world is turned upside-down by this shocking revelation. You're being pulled and tugged in a million different directions, and through it all you fight through your growing attraction- and fear- for the man who took you, even though he's more beast than he is human.
Guy: You're a werewolf. Not the bitten kind, the born kind. Your pack lives in the forest surrounding the town. There's a treaty that basically says that the werewolves will leave the townspeople alone and vice versa. But if a human enters the forest, they belong to the pack. One night, while you patrol, a new girl to the town enters the forest and you claim her before your pack mates. You show her your pack, keep her safe from the harsher wolves, the ones that dislike humans. Along the way, you discover for the first time exactly what it means to be human.
Also, I have a thing that must be explained.
You know the inner voice everyone has, like a conscience that tells them right from wrong? Well, werewolves have that too, but theirs is broken. They don't have an off switch, and their inner voice is angry, horny, and slightly violent. It's also very persuasive. Depending on how a wolf is raised, that voice can either be tamer or wilder. When the inner voice is wilder, it's harder to ignore, thus creating a werewolf that is moody, easily frustrated, and a bit bipolar. Someone who is harder to control.
---------------------------------------
It’s the year 2285, and the world is in turmoil. The U.S. Has been shunned by the rest of the civilized world and has become a dictated union. Global warming, world wars, and economic collapse have turned the States into one of the most dangerous places to live. Only 1% of the population is wealthy enough to have homes, cars, decent food and clean water. The rest of the country is living in half-homes and has to scavenge every meal.
This dictatorship locks away dissenters, the sick, the old, and the mentally unstable in concrete prisons underground. The food is poor, the living conditions are nowhere near humane. One girl among these prison outcasts is treated especially terrible. At a very young age, she developed a power that made it impossible for anyone to touch her skin. The government didn’t know what to do with her, so they tossed her in prison to let her rot. Now, ten or more years later, the government finds that they need information about a certain Resistance group. They can’t torture it out of the prisoners in any traditional way… so what if they use her? They send their young, up and coming general to collect her. He enters her cell to find a mad creature, incapable of speech and the most basic human interaction. He thinks her a beast, a monster for her curse and the job she’s given. But will that change in the next few weeks as he wipes away the grime and teaches her how to be human again?
---------------------------------------------
The world has fallen to ruins. Very little people have survived. People can't remember everything about themselves. They're all lost, and confused, trying to survive. Day by day each person goes to find their own Pieces. Each person's Pieces eventually become an object that will completely restore their memories. These Pieces are hidden throughout the world, and each person's Pieces look different. Some people are out to destroy other people's Pieces, or help others find them while they look for their own.
This has been immensely successful for me in the past
So this would be a good few years after the apocalypse.
There are little towns and settlements.
To be clear, let's say that everything short of zombies and aliens destroyed most of humanity. Earthquakes, tsunamis, biological warfare, the whole shebang.
The way I have done this in the past is that the male character is a bounty hunter, or a mercenary. He's being paid to either kill or capture the female character for whatever reason. The world was inherited by psychopaths, so they might just want her because she's pretty.
Obviously, he finds her, and stuff happens.
