Life Eternal (Camren)

Sequel of Dead Beautiful:
Camila Cabello has changed. When she looks in the mirror, a beautiful girl with an older, sadder face stares back. Her condition has doctors mystified, but Camila can never reveal the truth: she died last May, and was brought back to life by the kiss of her Undead soul mate, Lauren Jauregui.

Now, her separation from Lauren becomes almost unbearable. Her second life is close to an end, and each passing day means one less that she will spend with the girl who shares her soul.

Just when Camila has almost given up hope, she learns of the Nine Sisters-brilliant scholars who, according to legend, found a way to cheat death. She can't shake the feeling that they are somehow connected to her dreams, strange visions that hint at a discovery so powerful, and so dangerous, that some will stop at nothing to protect it.

Camila thought she knew the truth about life and death. But there is a secret woven through history that holds the only hope for Lauren and Camila. Unless they find answers soon, their time together is doomed to be cut short.

Just to reiterate, this is a converted fic, so 98% of the rights go to the author and the 2% stay with me cuz that names, and little pieces of info that makes the whole thing flow especially with the gender changes.
