Dunst Till Dawn

Indiana Jones meets Brandon Sanderson
Jack and Dawn Dunst own a business that finds anything from the mundane to the magical. But on what appears to be a series of seemly separate missions they start finding that they are more connected than they at first seem. And they find themselves involved in battle between very powerful clandestine organizations. An encounter that will have them discovering lost forbidding knowledge that will make them question the fabric of reality itself. Knowledge that seems more like magic than science. Such as parallel worlds, elemental transmutation, and an understanding of reality that show that reality is far more complicated than they ever imagined.
