I first became aware of him and this novel by reading a 2014 article he wrote for Gizmodo called How to Write a Great Science Fiction Novel in 7 Easy Steps and, as far as I can tell, “Lexicon” is the first SciFi novel he ever published, though he’s written other books before.
The novel is intriguing in that words are used as weapons, and they can ultimately kill. It’s a lot more complicated than that, but as it turns out, there are certain individuals who, properly trained, can analyze the personality “segment” of people around them, determining which words (which in the book are all nonsense words) will influence them.
But it’s worse than that. A teenage girl named Emily Ruff, who is a runaway and homeless in San Francisco at the beginning of the story, is recruited by a mysterious group of people and begins training at an exclusive prep school in Virginia (think “Professor Xavier’s School for Gifted Children” except the children are especially persuasive, but not mutants).
