Deadringer

For 100 years, the spirit of a great hero has lain in wait, biding their time to return to assist the next valliant warrior who should find his resting place. What he didn't bank on was for a 15 year old nerdy kid to find it instead.
When teenage Ben Price takes a silver ring from a haunted grave, he finds himself equipped with an arsenal of Necromancy spells, as well as a reluctant mentor, in the form of the undead spirit of a wisecracking gunslinger named Arthur. Tension rises at first, but when an urban legend comes to life and threatens their home with total destruction, Ben and Arthur must put their differences aside to get the world out of a grave situation. Literally!
