Love in the Falls: Sam & Camden

Earth has become a giant water bowl, and Phoenix - the last city of the surviving human civilization - is resting safely at the bottom of the vast ocean in a cocoon created by the song of Sian, Erin and Ivan. The three of them, despite appearing mostly humanoid, are much more than meets the eye. In their DNA are interwoven millennium of knowledge of long forgotten civilizations and Pantheon of Gods. The whole world building of the book is a fascinating mix of post apocalyptic, paranormal, sci fi fantasy elements with a healthy dose of the author's wild imagination. Cian is finally able to follow the pull of his heart and find his mate. I have always been partial to this main character and his loneliness was deeply touching to me. But this book is his song and I am happy for him. The chapters follow a pattern of time travelling which was a little bit anticlimactic to my own reading preferences and I couldn't fully sink into the right mind space and enjoy the experience. The plot is heavily action packed and follows more than one story thread and more than one character. It also taps in the deepest dark recesses of the human mind and how far people can sink in order to guarantee their own survival and keep the power to themselves. I am referring here to the Disciples of Annunaki on the Moon and the gruesome picture Cian found when he finally reached it. The search for his mate turned into a full blown rescue operation and a lot more secrets revealed.
If you're looking for unusual sci fi heavy on the plot and less on the smut, that's a good choice. The books however have to be read in order because they are closely interconnected and the main characters are more than cameos when they pop into the different stories.
