Actual rating: 3.5 stars. Thanks to NetGalley and Clarion Books for the arc of Black River Falls by Jeff Hirsch! A quarantine due to the virus called Lassiter’s has occurred. Lassiter’s is short for Lassiter’s Viral-Induced Retrograde Amnesia. The virus hit on October 16th, when people of all ages lost their memories and couldn’t even remember their families. Narrated by Cardinal Cassidy, Cardinal tells the story as if he’s writing/talking to his brother. Cardinal hasn’t contracted the virus and therefore, hasn’t lost his memory. He meets his mom in town, but she doesn’t seem to recognize him and she is living with a man that is not Cardinal’s father. He rescues a young woman from men pretending to be her husband and friend (a scheme men have thought up to capture women). The secret of the virus’ origins is revealed to Cardinal and he has the choice of revealing it to Dr. Lassiter and helping find the cure or ignoring the information and going on with life as it is right now. Sci-fi and dystopian fans will enjoy this book with the clever world building and character development.
