Highborn begins with a vividly described scene of Hell. Astarte, a fallen angel, watches the daily round of horrors from her bloodstained tower, and decides she wants out. We then cut to Astarte, having escaped Hell and calling herself Brynna Malak, as she adjusts to life in modern-day Chicago. Brynna can understand any language she hears. She’s less adept at navigating other aspects of human life: how to feel empathy, how to pet a dog, and why you shouldn’t just wander away from the scene when you witness a murder.
