Felicity: The Sixteenth Life

Stuck in an unending loop of reincarnation, a child faces playful and cruel fates jumping from one life to another. Even after living fifteen lives of differing identities, social status and even gender, this child had never lived past the age of twelve.
Currently on the sixteenth life, the child is named Felicity and was born as the illegitimate and unwanted daughter of a Count. She had already accepted the fact that she was cursed after the fifth reincarnation thus as she welcomed her eighth birthday, she waits for the future to unfold. Her 'death' has no precedent time for she had experienced death as young as age six.
If there was one thing she wished to do, it was to uncover the reason why she had been cursed with multiple lives, doomed to live in suffering and dying young.
However, a child is powerless. In addition to that, she had been a commoner for all the past fifteen lives. What can a commoner child do to possibly learn supernatural phenomena?
Thus, she was glad to be born a noble for once but of all the blasted luck in the world, she had to be born illegitimately and as a female.
However, she would not give up on life before she actually dies. She will try her best to live past twelve years old like she had always done and perhaps even make it as an adult capable of investigating her strange predicaments.
Ifever she dies as Felicity and never reincarnates, then it would be none of her problem. At least she wouldn't know about it and the cursed loop would finally be over.
However, after one of her half-siblings wanders near the cottage where she peacefully lived her simple daily routine whilst waiting for the verdict of life or death, things suddenly begin to change...
