About the Author

Jennifer Lynn Barnes

I'm a Jennifer who goes mostly by Jen, an Oklahoma girl who's also lived in Connecticut and England, and a writer who has a not-so-secret double life as a cognitive scientist. I love pop culture, mythology, science, superheroes, Joss Whedon, guacamole, television targeted at teenagers, and any song that I know the lyrics to. I have no sense of direction, but can read a book and shower at the same time. As is probably obvious, I do not particularly excel at writing my own bios.

I started writing professionally when I was a teenager and completed my first four published novels while I was in college. Since then, I've split my time between various graduate programs and writing books. In May 2012, I graduated from Yale University with a PhD in Developmental Psychology, which basically means I spent a lot of time thinking about the way the mind works and designing and running experiments that probe the way that young children and non-human primates view the world. My background in the psychological sciences has a habit of working its way into the books I write, sometimes in unexpected ways.

As a reader, I love strong female characters, books that blend emotional depth with sarcasm and humor, and supernatural stories that feel real. I'm a sucker for romance and search out authors who can write action sequences and violence without pulling their punches.
