Escape is only a deadly journey away. Be careful what you create. It could kill you. At first, seventeen-year-old Lauren Knowles is thrilled to wake up in Alrujah-a digital fantasy world she created with her best friend, Oliver Shaw-but the exhilaration of serving as a magical princess in her own video game fades as she senses a demonic force lurking in the shadows. Though they designed a world of wondrous beauty-blue-leaf forests, shimmering silver rivers, and expansive medieval castles-Lauren and Oliver soon find their secret realm to be an ever-changing land of dark oppression and deadly sorcery. With the help of Aiden Price and Erica Hall, fellow gamers from their high school in North Chester, the four teens must find a way out-a way that can only be discerned from the dusty pages of the ancient leather-bound tome, the Book of Thing to Come. Faced with questionable allies, invisible enemies, and increasingly dangerous levels of difficulty, the four must learn to forge alliances, battle side by side, or stay forever lost.
