Next Sci-Fi entry for #CoSoBooks is The Icarus Hunt, by Timothy Zahn.
Timothy Zahn does space opera like few can. He wrote a bunch of Star Wars books that are considered best in the extended universe (now these books are no longer canon) but I think The Icarus Hunt was one of his strongest books.
The story is self contained and follows a "Han Solo" in all but name. The most important part is that it has an *extremely* satisfying ending which makes it all worthwhile.
One if my all time favs.
