I was charmed by Ivy and even with the preface assuring me that W.L. George was known to be progressive I was cringing and waiting for her to be brutally murdered, especially after she tries to get them out and her boyfriend insists on continuing. It strikes me that horror as a genre really has to work on its conventions in re: female characters, that I was so strongly expecting her to be killed for being sassy and female.
The reveal was fun and pleasingly inexplicable. I enjoy a bit of cosmic absurdity, especially in a horror piece this length.
