The powerful Bloodstone is in dangerous hands. And a deadly new threat rises. Ria and Rani have barely settled into their new lives at the palace--as princesses, as sisters--when a sinister prophecy uproots them once more. The Blood Moon will rise in one month's time, and with it their enemy Amara's opportunity to destroy everything Ria and Rani hold dear. The twin princesses must find Amara--a deadly search that separates Ria and Rani once more and takes them to wintry kingdoms and scorching deserts, pitting them against ancient mysteries and trap-ridden labyrinths, lethal sea monsters and an elusive enemy that steals into their very dreams.
