The Guardian : Derailers Book

The railroad opened the West to dreamers, fortune-seekers, and anyone looking to start over. It also offered a tempting target for ruthless thieves with no respect for human life. It would take a special breed of protector to keep the train running safely through outlaw territory.

Dylan Curry robbed trains before the war that changed him forever. After the Union was repaired, he needed a job that would legally employ his unique skills&#8212and Dylan Curry was reborn as "the Guardian." Now the plainclothes train marshal uses the skills with the six-shooter he honed as an outlaw to protect the trains he once treated as targets. But Dylan's past is galloping up to get him&#8212aided by a woman who blinds him with her beauty and lies. And it will take more than the Guardian's legend and his gun to keep this train from barreling off its tracks.
