Cannonball Express 3: Train Robbers of Mars - Cannonball Express: A Sci-Fi Western Book Series, #3

"Wow! It's BUFFY meets FIREFLY on Mars with trains!"Barry J. Hutchison, bestselling author of SPACE TEAM  The Cannonball Express. On the wild-west railroads of Mars, no other locomotive can touch her. As far as engineer-owner Jess Flint is concerned, friends and family are the only things she loves more. So when somebody goes and steals Jess's steam-powered pride and joy, pity the robbers. Because now it's up to Jess and her best friend Sally to saddle up, follow those departing rail wagons, and teach some blackhats a goddamn lesson in civility. Well...
that was the plan. What wasn't the plan was infiltrating mysterious underground bunkers, escaping deadly flesh-stripping acid baths, and becoming a two-gal snack for Mars's biggest and hungriest critter. All while neglecting to wear anything other than their pajamas. Oh, and let's not forget the impending nuclear catastrophe our two unlucky heroines inadvertently trigger, set to vaporize thousands of innocent Martian colonists in a single blast.
