I use the word unique so often to describe some Fantasy and some authors that... I no longer think of Ms. Vincent as unique, but rather unusual. Every work of hers that's I've found in my hands, whether I liked it or not, has always left an impression, because it is so unusual. There are no worlds out there like her worlds, no characters like her characters. 
 Menagerie is much the same. The setting and the characterization is so unusual, I couldn't help but be intrigued, and remain intrigued. Delilah lives in a sorta post-apocalyptic/posttraumatic/post-cataclysmic world where it was discovered that not all creatures inhabiting the world are human, that some are actually all sorts of paranormal creatures - Fae, selkies, shape shifters, creatures from Greek mythology... All sorts. In this world, they are discriminated against, and kept in travelling circuses as morbid attractions, or research facilities that are more like concentration camps, where humans perform experiments on them. They have less rights than animals, actually. 
 Delilah has always known herself to be human, until it was discovered she wasn't. Menagerie basically follows Delilah and the stories of the other non-human creatures she meets after she's incarcerated in a travelling circus. 
 Fantastic read. However, one thing bothered me greatly. I do not know whether Ms Vincent set out to write an allegory or not, but this book reads like an allegory of slavery. Which is where my problem lies. Enslaved black people were not other; they were not a different species; they weren't a danger to anyone. They were human. In fact, they were the exact same type of human as their Enslavers. So to have a tale that tells the injustice of slavery, but have the victims of this injustice be of a clearly different species (non-human), and in many cases, actually dangerous entities... No. Neaux. Nope. Nah. Didn't sit well with me at all. 
 To be fair, it may not have been Ms Vincent's intention to write an allegory, but I dare anyone to read it and declare that they never once thought of chattel slavery or the Civil Rights Movement. Then I'd call you a liar. So... Yeah. Fantastic story, but with that Gigantic caveat.
