For Leonardo, a librarian with neither time nor money for a real vacation, books are his only escape. But everything changes on his birthday when a student gives him Source Code, the most immersive VRMMORPG of the moment. "I prefer books; at least they let me travel with my imagination," he objects, skeptical. She smiles. "That's exactly why I gave it to you. If you can't take a vacation in the real world, take one in Source Code." As soon as Leonardo logs into Source Code, an unexpected twist threatens to ruin his virtual vacation. Will he finally experience the getaway of his dreams, or does Source Code conceal challenges far greater than he ever imagined?
