Fenrir – Eric Flint & Ryk E. Spoor

Astronomer Stephanie Bronson discovers a interstellar object approaching the Solar System. It turns out to be an alien spacecraft, soon dubbed “Fenrir”, which remains stubbornly silent. As the spacecraft is decelerating, it suffers an apparent catastrophic malfunction. A bold rescue plan is put in place for the enigmatic alien intruder.

An excellent adventure story with high adventure and solid science. Mr. Flint and Mr. Spoor make the plot flow smoothly, with interesting characters, and very engaging prose. Reminiscent of, and purposefully calling back to, a more optimistic time. I thoroughly enjoyed it.
