Wormwood Dawn - Edward Crae - Bog

As Dan begins adjusting to life in the new colony, it is discovered that Jeff and his crew have lost contact with Drew, Royce and Cliff. Their hastily-assembled rescue team, which includes an old friend Dan thought was dead, sets out to find out what happened. Little does Dan know, two new friends have traveled back to our universe with him, but find themselves in the middle of an alien invasion.
As Dan and friends travel back to Brown County, they come in contact with a long-isolated physicist who may hold the answers to closing the portal for good, preventing the Soul Eater from destroying our universe as we know it. His dreams introduce him to an ancient force for good that may give him the power to do so.
