My Calamity Jane - Cynthia Hand

Welcome to America in 1876, a land teeming with gunslingers, outlaws, and ghouls, better known as werewolves.
And where there are ghouls, there are hunters: none other than the one and only Calamity Jane, joined by her fellow stars of Wild Bill’s Traveling Show — Annie Oakley and Frank 'Pistol Prince' Butler.
After a hunt for ghouls goes south and Jane discovers a suspicious bite on her arm, she heads back to Deadwood, where rumors of a cure for the ghouls are circulating. But rumors can be misleading — which means the gang better catch up with her before they’re a day late and Jane’s gone for good.
