The Return [Heritage of Horror Book 1]

After their older brother dies in one of the first battles of the Revolutionary War, sixteen-year-old twins Molly and Jacob Gray discover a way to bring him back to life. The initial side effects (including a marauding zombie arm) seem to disappear in a couple of days, so when Molly's boyfriend is run over by a wagon, they decide to resurrect him as well. Only too late do they find out that they have turned the two people they love the most into the living dead.
