Dan and Liz are two college freshman, boy/girl twins, who unexpectedly get caught up in a parallel world called the Realm. The people of the Alliance had existed in and around the known world for centuries, though they had not yet been revealed to humans. Their long era of peace is about to come to an end, however. Lianco's evil brother Serenu wants revenge, and the twins suddenly discover they are the Alliance's only hope for preventing his retribution from destroying an entire civilization. Strength, loyalty, and trust must show them the way, and failure is not an option.
