The Quiet at the End of the World features two characters who study STEM, just like my other books (I have a niche, and it is intensely nerdy characters). This time, Lowrie, the protagonist, is an engineer and her best friend-slash-lifelong-crush Shen studies evolutionary biology. They are also both archaeologists, but they would never call themselves that. Lowrie has her own workshop full of tools and carries a supply around with her just in case there’s anything that needs fixing and/or breaking open. Shen has a permanent stack of books he wants to read, full of information he hopes will help him understand the crumbling civilisation around them. He’s not so great at the physical side of things, but he has Lowrie for that. She and Shen are the perfect team – skills and smarts, they call it.
