Countdown

I'm this world you are born with a timer. It is on your wrist, and it counts down to the second you will meet your soulmate. There are no second chances in this world. If they die, it stops. It will stay on your wrist forever, reminding you always that true love will never come for you.
Eva Baker was born without a timer, Luna Elder and Micheal Cleary have rainbow timers, meaning they're gay, and Lea Brightly's timer stopped at the age of eight, with ten years left.
When the four learn that the government is binging people the timers, they set off to stop them forever.
