A strong debut from Cadwell Turnbull, The Lesson does what all the best science fiction does: It uses the supernatural to reveal something true about our world. The book is set in the U.S. Virgin Islands five years after the Ynaa, an advanced alien race, arrived to study humans. The Ynaa live mostly peacefully with humans, at least for the time being. Most people are willing to put up with the occasional killing at the hands of the Ynaa in exchange for their science and medicine, but eventually enough is enough. Narrators Janina Edwards and Ron Butler do a fantastic job setting us in the islands, and their accents draw extra attention to the colonial elements of alien invasion that mirror our own history. It’s worth a listen for anyone with an interest in sci-fi.
