Heller (Luke Heller Book 1)

A damsel in distress, Wyatt Earp called her. And he was right, too. Because as soon as soon as Luke Heller got involved with the beautiful Irene Lawrence, he found himself up to his neck in murder, intrigue and a mysterious deal so big that it could only end—explosively—seven hundred miles away, on the notorious Barbary Coast.
En route, Heller found himself battling thick-armed bullies and bloodthirsty Chinese hatchet-men determined to give him a double profile. But for Heller—once a Confederate sharpshooter, big-city cop and Pinkerton detective—it was all in a day’s work.
Besides, as his enemies always found out, he wasn’t only a Heller by name—he was also a heller by nature.
