I very much enjoyed that the main character of this story is female, a capable character to carry the story and me along with it. Cassie is a scientist who believes this new-found alien technology is not for humans to adopt. What the Wormers left behind never seems to fit just right, with Man too eagerly grasping a Wormer puzzle piece and making it fit the picture according to the limited amount we know and think, and Cassie likes when things fit right into place, with no pushing or prodding to make an easy fit. Soon, Cassie is called on to solve a life or death puzzle, which also serves as a test set by the Wormers.
Who are the Wormers, and why does it seem these ancient people have led us to this particular planet with this particular puzzle to solve? These questions kept me turning the pages, waiting to see what was in store for Cassie and her crew. This story delivers a very good science fiction read, keeping me involved with just enough science that I am familiar with, yet at the same time, building on that science in an imaginative way, with a real story about the human need to explore and to figure things out.
This author was new to me until recently, when kindle freebies allowed me to get to know his work. I've since read a few of his stories and have come to appreciate how well he constructs a sentence and how well he crafts a story. He makes it look easy. With this story, he pulled me in and took me someplace interesting, reminding me of what I love about science fiction, that idea of an alien world and the mystery of an unknown people. A very enjoyable way to spend thirty minutes of my day.
