Roswell, Texas by L. Neil Smith
This is a graphic novel, set in one of L. Neil Smith’s Libertarian universes. In this reality, Santa Ana was killed by a long range rifle shot from the Alamo, allowing the people in to escape, and the Republic of Texas to survive. Flash forward to 1947. There is a mysterious crash near the Texas town of New Mexico. Four Texas Rangers are sent to investigate, along with various military units and spies from various nations, including the California Republic, the Third and Half Reich, and a much smaller United States. It’s a fun read, and Ranger William Bear doesn’t just get the girl, he gets the girl.
