Just finished Charles Sheffield’s Cold as Ice. Really, really, really good modern hard science fiction – highly recommended.
In a similar vein, I finished Planets of Adventure – old, almost antique science fiction by Murray Lienster. Definitely a little long in the tooth here and there, but the stories are pure gold.
Can’t find this book on Amazon.com, so it’s probably out of print. You can probably find or request a copy at your local library.
