Fifteen-year-old Wesley Conner and his 14-year-old sister, Anna, step inside their house one day to find their parents missing. After a vain police search, the siblings, and their best friend, 15-year-old Drew Vincent, an orphan since infancy, are taken into the foster care of the elderly Josiah Smith. Exploring the old man's house, the three teens discover a mirror that is a portal to another world-a world of knights, elves, dwarves, and strange creatures. They soon find themselves caught in a country that is on the brink of war, threatened by an evil elf lord. When their new friends at the Citadel enlist their help, offering to train them as knights, the teens accept, in hopes of finding their parents. But when the teens are assigned a quest to rescue a man, an elf, and a dwarf, they are soon caught up in a struggle much bigger than they ever could have imagined, one that will test their friendship, their courage, and their faith.
