On the run with nothing but his passport, his father's stolen wallet, and the clothes on his back, Tim Connelly meets a tall dark stranger. A stranger with shaggy hair, a sweet smile, and an enormous backpack, who calls himself "Argent." "It's the first thing that came up when I googled 'cool vampire names' when I was thirteen," he explains. Argent is traveling the world, and he invites Tim to come along for the ride. Shy, anxious Tim finds himself drawn into an unexpected adventure, contending with everything from giant snakes and swarms of hungry monkeys to angry ghosts. Most terrifying of all, Tim gradually realizes that he's falling in love with Argent.
