The Twenty-year Cycle

People say we have 13 lives, stating that our souls pass through 13 stages or lifetimes to complete one cycle of enlightenment. Depending on where you are in your 13 lives, you can determine the various roles you need to learn from at this stage in your spiritual development.
We are born, we grow up, we experience a crucial life, and we die. And then, we incarnate into a new living species. Hi, I'm Arzhel, a soul who has died 11 times and never lived the life I wanted. In this lifetime, I have one simple wish: not to die on my 20th birthday.
In each of my previous lives, I always die on my 30th birthday. What if I told you I'm in my 12th lifetime? And just like before, I died on my 20th birthday. I'm trapped in a cycle where I die in a mysterious way, always without knowing how it happens. Is it a mystery? A murder? Or am I just crazy?
In this lifetime, I'll solve the mystery of how I died in my previous lives. I want to know how I died. And one more thing how can I forget the love of my life, Nicholas, the man I truly love? Will I ever find my dear Nicholas? Will we have the happy ending we deserve? And most importantly, will I uncover and find the reason why I always die on my 20th birthday?
