As a life-long introvert, I grew up surrounded by extroverts and had to adapt accordingly. I knew what to do to get them to leave me alone; I knew how to feign excitement at social events that I found stultifying. I knew how to ignore ignorant comments from certain extroverts. For example, at the time of writing this, someone wrote on my timeline that introverts just lack social skills, which requires no response except a big-ass Gary Coleman side-eye.
Annihilation by Jeff VanderMeer is about introversion at its core. Allow me to explain in this spoiler-filled three minutes which are probably better spent buying the book. My reading is coloured by my work as a hospital psychiatrist, dealing with people who have attempted or are at risk of suicide. Passing fiction through a psychological prism is, for me, involuntary.
