This is our book group book for Saturday and I enjoyed rereading it. A scientist is badly injured in a station accident and receives many prostheses. Most people believe the accident was caused by a man and shun him. On their next missions, they inadvertently must work together. There's an object entering the Solar System, moving fast, endangering another station, and heading for the sun. They have to get inside and find out what it is. There's minute-to-minute excitement for the explorers, and I ended up reading it in three days instead of parceling it out over the week like I usually do for book group. Highly-recommended.
