Perian, Oracle to the Empires of Rashinder and Darna, barely survived the attack of Mage Armin, a madman bent on possessing him and taking control of both empires. Weak against the mage's power and battered to exhaustion by terrifying taunts, Perian struggles to strengthen his barriers against the invasion of his mind - and to grapple with the burden of his gift of foresight. When Perian has a vision of Rashinder's destruction, the cause is disturbingly unclear. With the empire's survival in the balance, he is forced from the illusory protection of Jasperen Castle to embark on a dangerous journey of unimaginable twists and turns that even he cannot foresee. As Perian and his loved ones fight to save the empires, and a mage more powerful than even Armin rises in search of revenge, Perian must master the realm of the seer and learn to wage his battles alone, in the space between worlds.
