O BLOOD

Olya is a freshman at med school. One day to her surprise she discovers she is not exactly human, but a unique creature from an alternative branch of evolution. She is an o-person. O-people's genetic code is a combination of human and octopus DNA. They have existed among humans undercover for centuries and created a social and behavioral system that allows them to be just like humans. O-people have superpowers such as highly advanced senses, tactile empathy, mimicry, and the ability to stay underwater for extensive periods of time. At the same time, 99% of O-women die while giving birth.

However, Olya turns out to be one of the 1% who can survive. As such she may be able to save her species and give mankind a second chance. As soon as Olya becomes a part of the O-world, she dives into a world of interspecies intrigues. It turns out that it's not just her own species who have plans for her. The secret service and scientists are onto her now, as well as a serial killer who targets O-women.
