After a tumultuous freshman year at Detroit University, Marlow Henry and Sage Farrell look forward to a calm, uneventful summer break. Not gonna happen. Before Marlow can even make his blossoming relationship with Dakota official, Sage pulls him into her new discovery – a math equation that opens a window in time and space. Then they witness a murder. Fate pulls them into a war-torn and deserted version of Marlow’s neighbourhood where they are forced to help a rebel group counterattack. The group’s ethics are questionable and Marlow has a personal reason to distrust the leader. Plus, members of their small community keep dying. The situation is more dire and twisted than Marlow and Sage can imagine. No one is safe. No one can be trusted. They don’t even trust each other. How can they save the world, if they can’t save themselves?

When you're dead wrong. Sage Farrell regrets missing her chance to be more than friends with Marlow Henry. But being alone and lonely in her sophomore year at Detroit University is the least of her problems. On a dark, quiet forest road something jumps in front of her truck, literally from out of nowhere. It wasn't a deer or elk that she hit, but the beautiful media star Crystal Morrisette. Marlow and Sage are pulled into yet another unexplainable mystery. Who killed the media star and how did she just appear out of thin air? And how are they going to prove to the police that Sage is innocent of this crime? There's a madman on campus getting crazier by the day and now his sight is set on Sage and Marlow. They have to put their heart issues aside until they find a way to stop him, because there's no sense falling in love if you're dead.
