Have you ever been so stressed out at work that your boss forces you to take a vacation? Ex-Navy Seal, Edward Tanner was. On a whim he decided to take an Interstellar cruise, see new worlds, experience new thrills, make new friends, and it turned out, connect with old ones. Maybe even learn how to control the debilitating headaches that have been ruining his life. But something from his past was coming back to haunt him, a past he couldn't remember. A past he would need to recall. Something he'd done that he had to make right, before people from that past killed him. And those headaches, they made him physically unable to fight back, even though the fate of the universe hung in the balance.
