War between the devas and the demons is imminent, and the Otherworld is on high alert. When intelligence from the human world reveals that the Sleeper is holding a powerful clairvoyant and her sister captive, 14-year-old Aru and her friends launch a search-and-rescue mission. The captives, a pair of twins, turn out to be the newest Pandava sisters, though, according to a prophecy, one sister is not true.
