James Winters just had his final night of sleep. Now, every time he closes his eyes, he falls into an alternate dimension of pirates, sorcerers, gunslingers, and runics. What begins as an escape from the routine of middle-school life soon becomes much more dire. After all, James isn't alone in his Travels. He has unwittingly entered a cosmic war between those seeking to save the countless worlds-and those bent on their destruction. James learns that the most important rule of being a Traveler is to never admit you don't belong. And never, ever let them follow you home. Now he is caught in a vise between real life and alternate realities. Can he master his newfound abilities as a Traveler? Or will his enemies discover who he is and where he's from? To save himself and his family, James must alter the fate of his adopted world. And he must do it alone. Because in the infinite worlds, where anyone can be anything, nothing is more perilous than trust.
