Lights Above Cass by Marilyn Brokaw Hall is a fascinating science fiction novel that is full of mystery, drama, and suspense. The blurb lures readers in with a scifi twist of a self-aware Quantum computer recovered from a crash, and then the book takes readers on a journey of questions, answers, secrets and revelations.Lights Above Cass is the first book that I have read by Marilyn Brokaw Hall and initially I was eager to dive into this book to see where the author was going to take me. The author begins the book with a thrilling and page-turning array of lights out near a secret military base, and a high speed aircraft zooming all over the place. My curiosity is piqued and I’m eager to learn what happens next. Then the story takes a twist and leaves me wondering where exactly are things going.Now, when I quickly learned that this story wasn’t shifting immediately to Lucia I was a bit disappointed at first. I was curious to see how she was recovered and how she played into all of this and how the author was going to work this in the story. But as the author instead gives me various characters who have disappeared one by one, my interest was quickly pulled back into the story. Each situation is different and unique and I loved how I got the impact on the lives of those who were left behind for all those years. My heart broke for the characters who had to report their loved ones missing, or simply, even worse, came home and they were gone with no explanation and forced to suffer for it.The way that this story is pieced together is really well-done. There were some parts with certain characters that I wanted to delve deeper with into their stories, but the author moves along at the right pace to keep the reader engaged with what and who comes next to keep the story moving along. I like how injustices are uncovered and secrets revealed in the right places.There isn’t much that I don’t like about this book. There are some places of where the storyline slows down a bit too much for my taste, but when it picks back up, which it does rather quickly, then it is truly fascinating and hard to put down. There are a few minor editorial errors (spellings missteps here and there) but nothing so drastic that it detracts from the story or interrupts the flow.While this book isn’t totally scifi, but is blended in so that you get more of a mystery/thriller/suspense novel it is still a really well-done novel. I am rating this book 5 out of 5 stars. I enjoyed the uniqueness of this author’s writing style and how they brought this storyline to life. If you like a science fiction novel with a nice dose of suspense and mystery then this book is a good choice to pick up. You won’t be disappointed.
