The Gunslinger

A scorned man accused Charlotte Bullion of being a Witch (without knowing that she is, in fact, a Witch) and sends the people of their town after her. Fearing for her life, Charlie digs through the spellbooks of her mother - and finds a summoning ritual for a Gunslinger named "Redhand".
The Gunslinger coming to save her isn't the original Redhand, though. She's the last descendant of a long line of cursed heroes, Genevieve Redhand. They make off together but despite having fulfilled the Quest she was summoned for, the bond between her and the Witch doesn't break.

Together, they try to find out why.
