Steam - The Legends Saga, #3

Time passes, sins forgotten. The bodies of the victims long since rotten. Trapped within the essence of the Headless Horseman by the guilt of slaughtering her best friend, Ireland Crane follows the father of science fiction, HG Wells, in search of freedom from the curse that binds her. Instead, she discovers even he has a hidden agenda. A dark, relentless passion to be reunited with the woman he loves has driven him to manipulate time and a murderous Horseman. Yet heed my warning, as the Raven flies, The Hessian will come .
and you will die. All that prevents Ireland from abandoning Wells' twisted pursuit, or introducing him to her sword, are the undead witches haunting her. Begging for freedom from a vile succubus, the ghoulish coven leads Ireland and her crew on a journey through Salem's sordid past. There, they learn there is more to Nathaniel Hawthorne's history than a scarlet letter, and the secret they've uncovered seeks to destroy them all.
