This is an interesting science fictional take on the Ina, Butler’s vampires. We learn about the Ina and their society from the viewpoint of Shori. The Ina are a fascinating group, with a culture and history that we learn alongside Shori.
Rather than the comfortable norm for vampires, Shori looks very young (which brings up Lolita like concerns), is small, and black. Her control of her victims is due to a venom which has several interesting side effects. It’s interesting looking at these near traditional vampires through a more scientific lense. Similarly, the social groups they build feel realistic, and in context their withdrawal from society makes perfect sense.
Interestingly, as the book goes on, we begin to transition from traditional vampire (and sympathetic vampire) books and start getting involved in genetic engineering ethics and race. It makes sense in the book, despite the shaking your head you’re probably doing.
In the end, it’s an interesting and fun book with deeper overtones, if you’re looking for them.
