I picked this up a while back, during the launch period, and didn't have the time to read it until months later.
However, even after several months, I have found myself surprised, again, by Sabrina Voerman's writing style. Her first book was already a lovely, funny, enjoyable, and sometimes dark twist on a fairytale. This, is no different, and encompasses a lot of dark themes.
Mermaids are hunted and killed, their meat is harvested. There are emotional storylines of different people. There are even tints of human greed, exploitation, the murder of one's own kin (In this case, vampires hunting and killing their own) that are told through two different characters. Nikolai, the vampire, and Æsa, the siren. It interwines with fantasy and dark fantasy, and not only did Voerman have already an arsenal that was surprising, in terms of historical accuracy with her first novel, but I realized, she even has great worldbuilding and fantasy-versed skills that take you into dark, grim little places that you wouldn't really expect. You look at the cover, it's a blue, and somewhat welcoming cover. Fresh, not really dark or harmful. And then, just as you think it'll be a light read, you get sucked straight into a dark and completely devastating world filled with all sorts of different takes on humanity, greed, hatred, slaughter and murder, economical greed, consumption, and much, much more.
5/5, has become one of my few favorite authors.
